rust-gc is a simple tracing (mark and sweep) garbage collector library for Rust, providing a Gc smart pointer similar to Rc but with cycle collection. Types placed in Gc must implement Trace and Finalize traits, typically via a derive macro.

Use cases

• handle reference cycles in Rust data structures
• garbage collect cyclic graphs in Rust
• use a Gc pointer like Rc but with cycle detection
• implement custom finalizers for collected objects
• build interpreters or language runtimes in Rust needing GC

When to choose

• you have cyclic data structures that Rc cannot handle
• you want a small, simple GC library integrated with Rust's ownership model
• you are building a language runtime or interpreter in Rust

When to avoid

• Rc, Arc, or Box would suffice for your data structures
• you need a high-performance or concurrent production-grade GC
• you want to use it pervasively rather than only where needed
