Trait Method 

pub trait Method<S, P, R>: Sealed {
    type Future: Future<Output = R> + Send;

    // Required method
    fn invoke(&self, server: S, params: P) -> Self::Future;
}

A trait implemented by all valid JSON-RPC method handlers.

This trait abstracts over the following classes of functions and/or closures:

Signature	Description
async fn f(&self) -> jsonrpc::Result<R>	Request without parameters
async fn f(&self, params: P) -> jsonrpc::Result<R>	Request with required parameters
async fn f(&self)	Notification without parameters
async fn f(&self, params: P)	Notification with parameters

Required Associated Types

type Future: Future<Output = R> + Send

The future response value.

Required Methods

fn invoke(&self, server: S, params: P) -> Self::Future

Invokes the method with the given server receiver and parameters.

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<F, S, P, R, Fut> Method<S, (P,), R> for F

where F: Fn(S, P) -> Fut, P: DeserializeOwned, Fut: Future<Output = R> + Send,

Support JSON-RPC methods with params.

type Future = Fut

impl<F, S, R, Fut> Method<S, (), R> for F

where F: Fn(S) -> Fut, Fut: Future<Output = R> + Send,

Support parameter-less JSON-RPC methods.

type Future = Fut
