Internal JSON-RPC 2.0 transport over HTTP.

Implementations

impl RpcTransport

pub fn url(&self) -> &str

Get the URL this transport connects to.

pub fn timeout(&self) -> Duration

Get the timeout duration for this transport.

pub fn new(url: String, timeout: Duration) -> Self

pub async fn call<T: DeserializeOwned>( &self, method: &str, params: Value, ) -> Result<T, Error>

pub async fn call_optional<T: DeserializeOwned>( &self, method: &str, params: Value, ) -> Result<Option<T>, Error>

Call a JSON-RPC method that may legitimately return no value.

Treats both "result": null and a missing result field as Ok(None), while still propagating JSON-RPC errors.

pub async fn call_void(&self, method: &str, params: Value) -> Result<(), Error>

Call a JSON-RPC method that returns no meaningful value.

A null or missing result is accepted without error. Only JSON-RPC error responses are propagated.
