The node behind the RPC server.

Implemented by the DIG node; consumed by RpcServer.

Provided Methods

fn handle<'life0, 'async_trait>( &'life0 self, method: Method, params: Value, ) -> Pin<Box<dyn Future<Output = Result<Value, RpcError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Handle a resolved method call, returning a result value or a canonical error. params is the raw JSON-RPC params (Null when absent) — the handler deserializes it into the method’s params type from dig_rpc_protocol::types.

The default implementation rejects every method with -32601, so a handler need only override the methods it actually serves (its profile).

fn healthz<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), RpcError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Liveness probe backing the HTTP GET /healthz route. Ok(()) ⇒ the node can serve. Default: always healthy.

fn version(&self) -> String

The node’s software/API version, embedded in the generated OpenRPC document served by rpc.discover. Default: this crate’s version.

Dyn Compatibility

This trait is dyn compatible.

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