Struct sc_service::RpcHandlers[][src]

pub struct RpcHandlers(_);

RPC handlers that can perform RPC queries.


impl RpcHandlers[src]

pub fn rpc_query(
    mem: &RpcSession,
    request: &str
) -> Pin<Box<dyn Future<Output = Option<String>> + Send>>

Starts an RPC query.

The query is passed as a string and must be a JSON text similar to what an HTTP client would for example send.

Returns a Future that contains the optional response.

If the request subscribes you to events, the Sender in the RpcSession object is used to send back spontaneous events.

pub fn io_handler(&self) -> Arc<MetaIoHandler<Metadata, RpcMiddleware>>[src]

Provides access to the underlying MetaIoHandler
