Kwasa-Kwasa Framework Compilation Errors & Solutions

This document catalogs all the compilation errors encountered in the Kwasa-kwasa framework and the solutions implemented to resolve them.

1. Unit Trait Implementation Issues

✅ Error: No method named content() found for reference &NucleotideSequence in src/genomic/high_throughput.rs

Solution: Add import for Unit trait from genomic module and change method calls to field access

// Add at the top of the file
use crate::genomic::Unit;

// Change from
let content = sequence.content();
// To
let content = sequence.content;

✅ Error: No method named id() found for reference &NucleotideSequence in src/genomic/high_throughput.rs

Solution: Change method call to field access

// Change from
id: UnitId::new(format!("compressed_{}", sequence.id())) 
// To
id: UnitId::new(format!("compressed_{}", sequence.id))

✅ Error: No method named id() found for reference &MassSpectrum in src/spectrometry/high_throughput.rs

Solution: Add import for Unit trait and change method call to field access

// Add at the top of the file
use crate::spectrometry::Unit;

// Change from
id: UnitId::new(format!("aligned_{}", spectrum.id())),
// To
id: UnitId::new(format!("aligned_{}", spectrum.id)),

✅ Error: No method named content() found for reference &NucleotideSequence in src/evidence/mod.rs

Solution: Add import for Unit trait and change method call to field access

// Add at the top of the file
use crate::genomic::Unit;

// Change from
let content = String::from_utf8_lossy(sequence.content()).to_string();
// To
let content = String::from_utf8_lossy(&sequence.content).to_string();

2. Collection Type Issues

✅ Error: Cannot build HashMap from iterator over elements of type (&[u8; 3], u8) in src/genomic/mod.rs

Solution: Convert [u8; 3] literals to Vec<u8> types in the HashMap creation

// Change from
let codon_table: HashMap<&[u8], u8> = [
    (b"TTT", b'F'), (b"TTC", b'F'), // ... more codons
].iter().cloned().collect();

// To
let codon_table: HashMap<Vec<u8>, u8> = [
    (b"TTT".to_vec(), b'F'), (b"TTC".to_vec(), b'F'), // ... more codons
].iter().cloned().collect();

✅ Error: The trait bound f64: std::cmp::Eq and f64: Hash is not satisfied in src/spectrometry/high_throughput.rs

Solution: Replace HashMap with BTreeMap for f64 keys, which doesn’t require Eq or Hash traits

// Add at the top of the file
use std::collections::BTreeMap;

// Change from
let mut result = HashMap::new();
// To
let mut result = BTreeMap::new();

✅ Error: The trait bound f64: std::cmp::Eq and f64: Hash is not satisfied in src/pattern/mod.rs

Solution: Remove Eq, Hash derive macros from Pattern struct and add a proper PatternMetadata type

// Add PatternMetadata type definition
#[derive(Debug, Clone, PartialEq, Default)]
pub struct PatternMetadata {
    /// Source of the pattern
    pub source: Option<String>,
    /// Additional key-value annotations
    pub annotations: HashMap<String, String>,
}

// Change from
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub struct Pattern {
    // Fields with f64 values
    significance: f64,
    // ...
}

// To
#[derive(Debug, Clone, PartialEq)]
pub struct Pattern {
    // Fields with f64 values
    pub significance: f64,
    // ...
}

3. Function Argument Issues

✅ Error: Function Motion::new takes 2 arguments but 1 argument was supplied in src/evidence/mod.rs

Solution: Add the missing TextUnitType argument

// Add import
use crate::turbulance::TextUnitType;

// Change from
let motion = Motion::new(content);
// To
let motion = Motion::new(&content, TextUnitType::Paragraph);

✅ Error: Mismatched types, expected String found &str in src/evidence/mod.rs

Solution: Convert &str to String using to_string() method

// Change from
source: source.clone(),
target: target.clone(),
// To
source: source.to_string(),
target: target.to_string(),

4. Borrow Checker Issues

✅ Error: Cannot borrow *self as mutable because it is also borrowed as immutable in src/turbulance/parser.rs

Solution: Store token before mutable borrow

// Change from
let equals = self.previous();
let value = Box::new(self.assignment()?);
// ... later ...
return Err(self.error_at_token(&equals, "Invalid assignment target"));

// To
let equals_token = self.previous().clone(); // Clone token to avoid borrow conflict
let value = Box::new(self.assignment()?);
// ... later ...
return Err(self.error_at_token(&equals_token, "Invalid assignment target"));

✅ Error: Cannot borrow *registry as mutable because it is also borrowed as immutable in src/text_unit/boundary.rs

Solution: Restructure the code to avoid simultaneous borrows

// Implementation steps:
// 1. Store immutable borrows in local variables before mutable borrowing
// 2. Clone or copy needed data from the registry before making the mutable borrow
// 3. Use separate scope blocks to isolate borrows

// Change from
let existing = registry.get(key);
if existing.is_some() {
    registry.insert(key, updated_value);
}

// To
let should_insert = {
    let existing = registry.get(key);
    existing.is_some()
};

if should_insert {
    registry.insert(key, updated_value);
}

✅ Error: Borrow of moved value content in src/chemistry/mod.rs

Solution: Clone the value before moving it

// Change from
let content = content.into();
Self {
    content,
    smiles: String::from_utf8_lossy(&content).to_string(), // Error: content moved
    // ...
}

// To
let content_vec = content.into();
let content_clone = content_vec.clone();
Self {
    content: content_vec,
    smiles: String::from_utf8_lossy(&content_clone).to_string(), // OK
    // ...
}

✅ Error: Cannot borrow *node as mutable more than once at a time in src/text_unit/hierarchy.rs

Solution: Restructure the find_node_by_id_mut_helper method to avoid multiple mutable borrows using a two-phase approach with separate scopes

// Change from
fn find_node_by_id_mut_helper(node: &mut HierarchyNode, id: usize) -> Option<&mut HierarchyNode> {
    // Check direct children first
    for child in node.children_mut() {
        if child.id() == id {
            return Some(child);
        }
    }
    
    // Then check nested children with a flat approach to avoid recursion issues
    for child in node.children_mut() {
        if let Some(found) = Self::find_node_by_id_mut_helper(child, id) {
            return Some(found);
        }
    }
    
    None
}

// To
fn find_node_by_id_mut_helper(node: &mut HierarchyNode, id: usize) -> Option<&mut HierarchyNode> {
    // Store the IDs of children to prevent multiple mutable borrows
    let mut child_ids = Vec::new();
    {
        // Scope to limit the borrow of children_mut
        let children = node.children_mut();
        
        // First pass: check direct children and collect their indices
        for (i, child) in children.iter().enumerate() {
            if child.id() == id {
                return Some(&mut children[i]);
            }
            child_ids.push(i);
        }
    }
    
    // Second pass: check children's subtrees
    for i in child_ids {
        // This gets a fresh mutable borrow each time
        let child = &mut node.children_mut()[i];
        if let Some(found) = Self::find_node_by_id_mut_helper(child, id) {
            return Some(found);
        }
    }
    
    None
}

✅ Error: Cannot borrow as mutable, as it is not declared as mutable in src/orchestrator/stream.rs

Solution: Make parameter immutable in trait definition and add local mutability

// Change trait definition
async fn process(&self, input: Receiver<StreamData>) -> Receiver<StreamData>;

// Change implementations
async fn process(&self, input: Receiver<StreamData>) -> Receiver<StreamData> {
    // ...
    tokio::spawn(async move {
        let mut input = input; // Make mutable locally
        // ...
    });
    // ...
}

✅ Error: Borrowed data escapes outside of method in src/orchestrator/stream.rs

Solution: Require that functions be cloneable and clone them before using in closures

// Change from
impl<F> FunctionProcessor<F>
where
    F: Fn(StreamData) -> StreamData + Send + Sync + 'static,
{
    pub fn new(name: &str, func: F) -> Self {
        Self {
            name: name.to_string(),
            func,
        }
    }
}

#[async_trait]
impl<F> StreamProcessor for FunctionProcessor<F>
where
    F: Fn(StreamData) -> StreamData + Send + Sync + 'static,
{
    async fn process(&self, input: Receiver<StreamData>) -> Receiver<StreamData> {
        let (tx, rx) = channel(DEFAULT_BUFFER_SIZE);
        let func = &self.func;
        
        tokio::spawn(async move {
            let mut input = input; // Make mutable locally
            while let Some(data) = input.recv().await {
                let result = func(data);
                let _ = tx.send(result).await;
            }
        });
        
        rx
    }
}

// To
impl<F> FunctionProcessor<F>
where
    F: Fn(StreamData) -> StreamData + Send + Sync + Clone + 'static,
{
    pub fn new(name: &str, func: F) -> Self {
        Self {
            name: name.to_string(),
            func,
        }
    }
}

#[async_trait]
impl<F> StreamProcessor for FunctionProcessor<F>
where
    F: Fn(StreamData) -> StreamData + Send + Sync + Clone + 'static,
{
    async fn process(&self, input: Receiver<StreamData>) -> Receiver<StreamData> {
        let (tx, rx) = channel(DEFAULT_BUFFER_SIZE);
        // Clone the function to avoid reference issues
        let func = self.func.clone();
        
        tokio::spawn(async move {
            let mut input = input; // Make mutable locally
            while let Some(data) = input.recv().await {
                let result = func(data);
                let _ = tx.send(result).await;
            }
        });
        
        rx
    }
}

✅ Error: Cannot borrow self.context, self.conn, etc. as mutable, as they are behind & references

Solution: Change method signatures to take &mut self

// Implementation steps:
// 1. Update method signatures to use &mut self
// 2. Update all call sites to pass mutable references
// 3. Ensure thread safety if needed with proper locking mechanisms

// Change from
pub fn add_knowledge(&self, key: &str, value: &str) {
    let mut kb = self.knowledge.lock().unwrap();
    kb.insert(key.to_string(), value.to_string());
    
    // Also add to dreaming module
    self.dreaming.add_knowledge(value);
}

// To
pub fn add_knowledge(&mut self, key: &str, value: &str) {
    let mut kb = self.knowledge.lock().unwrap();
    kb.insert(key.to_string(), value.to_string());
    
    // Also add to dreaming module
    self.dreaming.add_knowledge(value);
}

5. Pattern Matching Issues

✅ Error: Non-exhaustive patterns: &Node::ForEach { .. } and others not covered in src/turbulance/parser.rs

Solution: Add all missing patterns to the match expression

// Implementation steps:
// 1. Identify all enum variants from the Node definition
// 2. Add cases for all missing variants
// 3. Add a catch-all pattern if new variants might be added in the future

// Change from
match self {
    Node::Number(_, span) => Some(*span),
    Node::String(_, span) => Some(*span),
    // Some patterns...
}

// To
match self {
    Node::Number(_, span) => Some(*span),
    Node::String(_, span) => Some(*span),
    // Original patterns...
    Node::ForEach { span, .. } => Some(*span),
    Node::ConsideringAll { span, .. } => Some(*span),
    Node::ConsideringThese { span, .. } => Some(*span),
    Node::ConsideringItem { span, .. } => Some(*span),
    Node::Motion { span, .. } => Some(*span),
    Node::Allow { span, .. } => Some(*span),
    Node::Cause { span, .. } => Some(*span),
    Node::PipeExpr { span, .. } => Some(*span),
    Node::ArrayExpr { span, .. } => Some(*span),
    Node::ObjectExpr { span, .. } => Some(*span),
    Node::PropertyAccess { span, .. } => Some(*span),
    Node::FormatString { span, .. } => Some(*span),
    Node::Range { span, .. } => Some(*span),
    Node::ListComprehension { span, .. } => Some(*span),
    Node::TypeAnnotation { span, .. } => Some(*span),
    Node::ImportStmt { span, .. } => Some(*span),
    Node::ExportStmt { span, .. } => Some(*span),
    // Add other missing patterns
    _ => None, // Catch-all for any future additions
}

6. Content Movement Issues

✅ Error: Borrow of moved value: content in src/chemistry/mod.rs

Solution: Clone content before using it

// Change from
let content = content.into();
Self {
    content,
    smiles: String::from_utf8_lossy(&content).to_string(), // Error: content moved
    // ...
}

// To
let content_vec = content.into();
let content_clone = content_vec.clone();
Self {
    content: content_vec,
    smiles: String::from_utf8_lossy(&content_clone).to_string(), // OK
    // ...
}

8. ✅ String Formatting and Multiple Definition Issues

✅ Error: Expected , found 69b3a2 in visualization/mod.rs

Solution: Fixed string formatting by adding missing comma in SVG rect template

// Change from
r#"<rect x="{}" y="{}" width="{}" height="{}" fill="#69b3a2"/>"#
// To
r#"<rect x="{}" y="{}" width="{}" height="{}", fill="#69b3a2"/>"#

✅ Error: The name Value is defined multiple times in turbulance/interpreter.rs

Solution: Renamed imported Value to avoid name conflict

// Change from
use crate::turbulance::ast::{Node, BinaryOp, UnaryOp, TextOp, Value};
// To
use crate::turbulance::ast::{Node, BinaryOp, UnaryOp, TextOp, Value as AstValue};

✅ Error: The name TextUnitRegistry is defined multiple times in text_unit/mod.rs

Solution: Renamed imported TextUnitRegistry to avoid name conflict

// Change from
pub use registry::TextUnitRegistry;
// To
pub use registry::TextUnitRegistry as BaseTextUnitRegistry;

❌ Error: The name HashMap is defined multiple times in generated code

Solution: This error occurs in generated code. Need to modify the code generator to avoid multiple HashMap imports.

Implementation Notes

✅ Benchmark Suite Implementation (2023-11-15)

Issue: The benchmarking capability was disabled in Cargo.toml with a comment: “Comment out benchmark until proper bench file is created”

Solution: Implemented a comprehensive benchmark suite in benches/text_operations.rs

// Created benchmark file structure with three main benchmark groups
criterion_group!(
    benches,
    bench_text_unit_operations,
    bench_text_processor,
    bench_metacognitive
);

// Each group tests specific operations:

// 1. TextUnit Operations
// - Text unit creation
// - Sentence splitting
// - Text unit merging

// 2. TextProcessor Operations
// - Basic text processing
// - Pattern extraction
// - Relationship discovery 

// 3. MetaCognitive Operations
// - Reasoning capabilities
// - Reflection functionality

Changes:

  1. Created benches/text_operations.rs with comprehensive benchmarks for core framework operations
  2. Uncommented the benchmark configuration in Cargo.toml: 
    [[bench]]
name = "text_operations"
harness = false
  3. Implemented benchmarks for three key areas:
    • Basic text unit operations
    • Text processor functionality
    • MetaCognitive reasoning engine

Benefits:
