Struct jsonrpc_core_client::transports::local::LocalRpc

pub struct LocalRpc<THandler, TMetadata> { /* private fields */ }

Implements a rpc client for MetaIoHandler.

Implementations

impl<TMetadata, THandler, TMiddleware> LocalRpc<THandler, TMetadata>where TMetadata: Metadata, TMiddleware: Middleware<TMetadata>, THandler: Deref<Target = MetaIoHandler<TMetadata, TMiddleware>>,

pub fn new(handler: THandler) -> LocalRpc<THandler, TMetadata>where TMetadata: Default,

Creates a new LocalRpc with default metadata.

pub fn with_metadata( handler: THandler, meta: TMetadata ) -> LocalRpc<THandler, TMetadata>

Creates a new LocalRpc with given handler and metadata.

Trait Implementations

impl<TMetadata, THandler, TMiddleware> Sink<String> for LocalRpc<THandler, TMetadata>where TMetadata: Metadata + Unpin, TMiddleware: Middleware<TMetadata> + Unpin, THandler: Deref<Target = MetaIoHandler<TMetadata, TMiddleware>> + Unpin,

type Error = RpcError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut LocalRpc<THandler, TMetadata>>, cx: &mut Context<'_> ) -> Poll<Result<(), <LocalRpc<THandler, TMetadata> as Sink<String>>::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut LocalRpc<THandler, TMetadata>>, item: String ) -> Result<(), <LocalRpc<THandler, TMetadata> as Sink<String>>::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut LocalRpc<THandler, TMetadata>>, cx: &mut Context<'_> ) -> Poll<Result<(), <LocalRpc<THandler, TMetadata> as Sink<String>>::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut LocalRpc<THandler, TMetadata>>, cx: &mut Context<'_> ) -> Poll<Result<(), <LocalRpc<THandler, TMetadata> as Sink<String>>::Error>>

Flush any remaining output and close this sink, if necessary.

impl<TMetadata, THandler, TMiddleware> Stream for LocalRpc<THandler, TMetadata>where TMetadata: Metadata + Unpin, TMiddleware: Middleware<TMetadata> + Unpin, THandler: Deref<Target = MetaIoHandler<TMetadata, TMiddleware>> + Unpin,

type Item = String

Values yielded by the stream.

fn poll_next( self: Pin<&mut LocalRpc<THandler, TMetadata>>, cx: &mut Context<'_> ) -> Poll<Option<<LocalRpc<THandler, TMetadata> as Stream>::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
