rust-samp

Write SA-MP and open.mp plugins in safe Rust instead of C++. The same source compiles to a single binary that runs natively on both servers; the macros hide the FFI boilerplate and ABI-correct marshalling for Linux (Itanium) and Windows (MSVC).

This is the main crate — depend on it from your plugin's Cargo.toml.

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.

crate-type = ["cdylib"]

[dependencies]
# Published as `rust-samp` to avoid name collision; aliased to `samp` so
# the import is short.
samp = { package = "rust-samp", version = "3" }

Minimal plugin:

use samp::prelude::*;
use samp::{SampPlugin, initialize_plugin, native};

#[derive(SampPlugin, Default)]
struct Hello;

impl Hello {
    #[native(name = "Hello_Echo")]
    fn echo(_amx: &Amx, text: &AmxString) -> bool {
        println!("{}", &**text);
        true
    }
}

initialize_plugin!(type: Hello, natives: [Hello::echo]);

Build for 32-bit (both servers are 32-bit):

cargo build --target i686-unknown-linux-gnu --release
cargo xwin build --xwin-arch x86 --target i686-pc-windows-msvc --release

Related crates in this workspace

• rust-samp-sdk — low-level FFI bindings (AMX VM, open.mp component ABI). Depend on it directly only if you want raw access without the macros.
• rust-samp-codegen — the proc macros (#[native], initialize_plugin!, #[derive(SampPlugin)]). Re-exported by rust-samp; no need to depend on it directly.
