Module bytecode 

Bytecode analysis module

Provides bytecode analysis capabilities using evmole and evm-disassembler:

• Function selector extraction
• Opcode disassembly
• Security pattern detection

Single-Pass Analysis

For best performance when you need multiple types of analysis (security, stats, disassembly), use analyze_bytecode which performs a single disassembly pass and reuses the result. For individual operations, use the standalone functions.

Example

use ethcli::bytecode::{analyze_bytecode, detect_security_issues};

// Full analysis (single-pass internally)
let analysis = analyze_bytecode("0x1234...", &bytecode, true, true, None);

// Or individual operations
let security = detect_security_issues(&bytecode);
