Usage

Basic Optimization Analysis

use verinode_contracts::optimization::{AIOptimizer, GasAnalyzer};

let env = Env::default();
let optimizer = AIOptimizer::new();
let analyzer = GasAnalyzer::new();

let contract_code = include_str!("your_contract.rs");
let function_signatures = vec!["function1".to_string(), "function2".to_string()];

// Analyze contract
let result = optimizer.analyze_contract(&env, contract_code, &function_signatures);
println!("Gas savings: {} ({:.1}%)", result.total_savings, result.savings_percentage);

// Generate detailed report
let report = OptimizationReport::new(&result, &env);
println!("{}", report.generate_markdown_report());

Advanced Pattern Recognition

from contracts.ai.pattern_recognition import AdvancedPatternRecognizer

recognizer = AdvancedPatternRecognizer()
result = recognizer.analyze_contract(contract_code)

# Generate insights
for insight in result['insights']:
    print(f"{insight['type']}: {insight['message']}")

# Save analysis
recognizer.save_analysis('analysis.json', result)

Gas Profiling

# Run advanced gas profiler
cargo run --release --bin advanced_gas_profiler -- --contract your_contract.rs --output profile.json

# Generate visualization
cargo run --release --bin advanced_gas_profiler -- --contract your_contract.rs --visualize gas_distribution.png
