A set of Rust crates providing link-time initialization, destruction, and scattered data collection macros (ctor, dtor, link-section, scattered-collect). It lets Rust code run before/after main and collect items across a linked binary via linker-managed sections.

Use cases

• run initialization code before main in rust
• register plugins or handlers at link time
• collect scattered items into a single section across a binary
• run cleanup code after main exits
• build a registry of items without explicit registration calls

When to choose

• you need C-style constructor/destructor semantics in Rust
• you want linker-managed registries or typed sections across crates
• you need code to run before main for setup or side effects

When to avoid

• you only need simple lazy initialization with std::sync::Once or LazyLock
• you want portable code without platform-specific linker tricks
• you need initialization ordering guarantees across arbitrary crates
