Helper trait that is used to execute ethereum rpc calls

Required Associated Types§

Source

type Request: DeserializeOwned + Send + Sync + Debug

The request type to expect

Required Methods§

Source

fn on_request<'life0, 'async_trait>( &'life0 self, request: Self::Request, ) -> Pin<Box<dyn Future<Output = ResponseResult> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Invoked when the request was received

Provided Methods§

Source

fn on_call<'life0, 'async_trait>( &'life0 self, call: RpcMethodCall, ) -> Pin<Box<dyn Future<Output = RpcResponse> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Invoked for every incoming RpcMethodCall

This will attempt to deserialize a { "method" : "<name>", "params": "<params>" } message into the Request type of this handler. If a Request instance was deserialized successfully, Self::on_request will be invoked.

Note: override this function if the expected Request deviates from { "method" : "<name>", "params": "<params>" }

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
