🥰 mycrush

mycrush is a pure Rust implementation of the CRUSH algorithm, converted from C with c2rust and then refactored for safety and WASM compatibility.

Features

• ✅ Pure Rust API - No C ABI compatibility layer
• ✅ WASM Compatible - Builds for wasm32-unknown-unknown target
• ✅ Safe Rust patterns - Uses Result types and safe abstractions where possible
• ✅ No symbol conflicts - Independent from the C libcrush library
• ✅ Modern error handling - CrushError enum instead of integer error codes

Building

# Regular build
cargo build --package mycrush

# WASM build
cargo build --package mycrush --target wasm32-unknown-unknown --release

# Run tests
cargo test --package mycrush

Status

The library has been successfully converted to a pure Rust implementation:

• All #[unsafe(no_mangle)] and extern "C" declarations removed
• Safe Rust implementations for helper functions
• WASM compatibility verified
• All tests passing

For detailed conversion notes, see PURE_RUST_CONVERSION.md.

Note

This library still uses some internal libc functions (malloc/free/memcpy/memset) but is WASM-compatible through the libc crate's WASM support. Future work will replace these with pure Rust alternatives.
