rust-samp-codegen

Proc macros that generate the FFI boilerplate for rust-samp plugins.

Not affiliated. Independent community fork of samp-rs. Not affiliated with, endorsed by, or connected to SA-MP, the open.mp (Open Multiplayer) project, or the upstream samp-rs repository. "SA-MP" and "open.mp" belong to their respective owners and are named only to describe compatibility.

Provides:

• #[native(name = "Pawn_Name")] — turns a Rust method or associated function into a Pawn-callable native. Generates the extern "C" wrapper, argument parsing via AmxCell, panic isolation, and the __samp_reg_* registration function. Detects Result<T, E> vs T return types automatically.
• #[event(name = "OnPlayerConnect")] — turns a Rust method into an observer of a Pawn callback. Parses the callback arguments like #[native] and runs the handler when the gamemode's public executes. Register the handlers in the events: [...] list below.
• initialize_plugin!(type: T, natives: [...], events: [...]) — emits the SA-MP entry points (Load, Unload, AmxLoad, AmxUnload, Supports, ProcessTick) and the open.mp ComponentEntryPoint, including the vtable definitions for both Itanium (Linux GCC) and MSVC ABIs. The natives and events lists are both optional.
• #[derive(SampPlugin)] — generates impl SampPlugin for T {} with all defaults.
