Why So Fast?

🦀 Native Rust Performance
   ├─ Zero-cost abstractions
   ├─ No GC pauses
   └─ Extreme memory control

📊 SoA (Structure of Arrays)
   ├─ Symbol attributes in separate arrays
   ├─ CPU cache-friendly
   └─ 5-10x faster than pointer hopping

⚡ Chained Symbol Index
   ├─ O(1) definition jump
   ├─ Pre-computed symbol chains
   └─ Replaces on-demand parsing

🔒 RwLock Concurrency
   ├─ 1000+ AI Agent concurrent reads

🚀 Quick Start

As a Library

use woolink::{SymbolUniverse, Symbol, SymbolId, UniverseBuilder};
use woolink::prelude::*;

// Create global symbol table
let universe = SymbolUniverse::new(100_000);

// Insert symbols
{
    let mut guard = universe.write();
    guard.insert_symbol(symbol)?;
}

// Concurrent query (supports 1000+ threads)
let guard = universe.read();
let sym = guard.get_symbol(SymbolId::new(42));

// O(1) definition jump
let (target, location) = guard.jump_to_definition(SymbolId::new(42))?;

Cross-package Resolution

use woolink::bridge::{CrossPackageResolver, ResolutionResult};

let resolver = CrossPackageResolver::new(universe);

// Resolve cross-package reference
let result = resolver.resolve("github.com/gin-gonic/gin.Context", "main.go")?;
match result {
    ResolutionResult::Symbol(sym, loc) => {
        println!("Found at: {:?}", loc);
    }
    ResolutionResult::Redirect(target) => {
        println!("Redirect to: {}", target);
    }
}

CLI Usage

# Build index
woolink index ./my-project

# Query symbols
woolink query "NewClient"

# Show statistics
woolink stats

# Cross-package resolution test
woolink resolve "pkg.Symbol" --from "main.go"

# Export symbol table

💡 Use Cases

IDE Definition Jump

User clicks symbol → woolink jump → Returns definition location
Latency: O(1) = ~8ns
Experience: ✅ Instant jump, imperceptible delay
Comparison: gopls needs ~100ms to re-parse

AI Agent Concurrent Analysis

// 1000+ AI Agents querying symbols concurrently
let universe = Arc::new(SymbolUniverse::new(100_000));

let handles: Vec<_> = (0..1000)
    .map(|_| {
        let u = universe.clone();
        spawn(move || {
            let guard = u.read();
            let sym = guard.get_symbol(id);      // 8ns
            let def = guard.jump_to_definition(id); // O(1)
        })
    })
    .collect();

Cross-package Dead Code Detection

# Analyze symbol references across entire project
woolink analyze --project . --output report.json

# Find unused exported symbols
woolink deadcode --package "github.com/my/pkg"

Circular Dependency Detection

# Detect circular dependencies between packages
woolink cycles --project .

# Show dependency graph
woolink graph --format dot | dot -Tpng > deps.png
