bdwgc-rust
GlobalAlloc implementation for bdwgc, the conservative garbage collector.
This crate is for use cases in which developers need to integrate bdwgc into their programs written in Rust (e.g. writing a runtime library in Rust for their own programming language whose GC is done by bdwgc.)
Usage
See examples directory.
By default bdwgc is built with autotools. To build with cmake, enable the cmake feature:
cargo build --no-default-features --features cmake
