Struct JsonRpcWebSocket 

Source 
pub struct JsonRpcWebSocket { /* private fields */ }
Expand description

JSON-RPC 2.0 client layered on top of a WebSocket.

Assigns auto-incrementing request IDs and correlates responses by ID within a caller-supplied timeout.

Implementations§

Source§

impl JsonRpcWebSocket

Source

pub async fn connect(url: &str, profile: &BrowserProfile) -> Result<Self>

Connect to a JSON-RPC WebSocket endpoint.

Source

pub async fn call<P: Serialize, R: DeserializeOwned>( &mut self, method: &str, params: P, timeout: Duration, ) -> Result<R>

Send a JSON-RPC 2.0 request and wait for the matching response.

Returns the deserialized result field on success or an error if the response contains an error field or the timeout expires.

Source

pub async fn close(&mut self) -> Result<()>

Close the underlying WebSocket connection.
