Trait WireFunction 

pub trait WireFunction: 'static {
    type Request: Serialize + DeserializeOwned;
    type Response: Serialize + DeserializeOwned;

    const NAME: &'static str;
    const FALLBACK: FallbackPolicy;
    const SUPPORTED_VERSIONS: &'static [u32];

    // Required methods
    fn dry_run_request() -> Self::Request;
    fn dry_run_response() -> Self::Response;
}

Type-level specification for a wire function exported by a plugin.

Required Associated Constants

const NAME: &'static str

Name of the wire function (e.g., “sign”, “observe”).

const FALLBACK: FallbackPolicy

Compile-time fallback policy for this function. Must never be runtime-configurable to prevent security incidents (e.g., skipping signing).

const SUPPORTED_VERSIONS: &'static [u32]

Wire protocol versions this function supports. Host advertises max version, plugin chooses compatible version during handshake.

Required Associated Types

type Request: Serialize + DeserializeOwned

Request type for this wire function.

type Response: Serialize + DeserializeOwned

Response type for this wire function.

Required Methods

fn dry_run_request() -> Self::Request

Dry-run request for self_check (skip-handler model: serialize/deserialize round-trip only).

fn dry_run_response() -> Self::Response

Dry-run response for self_check (skip-handler model: serialize/deserialize round-trip only).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
