Plugins

The nautilus-plugin crate defines the plug-in artifact contract for NautilusTrader. It lets an independently compiled Rust cdylib identify itself with versioned build metadata and a manifest, and provides the C-ABI boundary primitives used at that boundary. It covers artifact identity and the boundary types only; it does not load, register, or run plug-ins.

:::warning The plug-in ABI is early alpha and the contract is unstable. Pin plug-in builds to the matching nautilus-plugin version. :::

A plug-in is a Rust cdylib that exports a single nautilus_plugin_init entry symbol. The nautilus_plugin! macro generates that symbol and the static manifest that carries the build identity:

nautilus_plugin::nautilus_plugin! {
    name: "example-plugin",
    vendor: "Nautech",
    version: env!("CARGO_PKG_VERSION"),
}

Set crate-type = ["cdylib"] in the artifact's Cargo.toml and depend on the matching nautilus-plugin version. See the crate docs for the boundary and manifest types.
