Struct jsonrpc_core::IoHandler

pub struct IoHandler<M: Metadata = ()>(/* private fields */);

Simplified IoHandler with no Metadata associated with each request.

Implementations

impl IoHandler

pub fn new() -> Self

Creates new IoHandler without any metadata.

pub fn with_compatibility(compatibility: Compatibility) -> Self

Creates new IoHandler without any metadata compatible with specified protocol version.

impl<M: Metadata + Default> IoHandler<M>

pub fn handle_request( &self, request: &str ) -> FutureResult<FutureResponse, FutureOutput>

Handle given string request asynchronously.

pub fn handle_rpc_request( &self, request: Request ) -> FutureRpcResult<FutureResponse, FutureOutput>

Handle deserialized RPC request asynchronously.

pub fn handle_call( &self, call: Call ) -> Either<FutureOutput, Either<FutureOutput, Ready<Option<Output>>>>

Handle single Call asynchronously.

pub fn handle_request_sync(&self, request: &str) -> Option<String>

Handle given request synchronously - will block until response is available. If you have any asynchronous methods in your RPC it is much wiser to use handle_request instead and deal with asynchronous requests in a non-blocking fashion.

Methods from Deref<Target = MetaIoHandler<M>>

pub fn add_alias(&mut self, alias: &str, other: &str)

Adds an alias to a method.

pub fn add_sync_method<F>(&mut self, name: &str, method: F)where F: RpcMethodSync,

Adds new supported synchronous method.

A backward-compatible wrapper.

pub fn add_method<F>(&mut self, name: &str, method: F)where F: RpcMethodSimple,

Adds new supported asynchronous method.

pub fn add_notification<F>(&mut self, name: &str, notification: F)where F: RpcNotificationSimple,

Adds new supported notification

pub fn add_method_with_meta<F>(&mut self, name: &str, method: F)where F: RpcMethod<T>,

Adds new supported asynchronous method with metadata support.

pub fn add_notification_with_meta<F>(&mut self, name: &str, notification: F)where F: RpcNotification<T>,

Adds new supported notification with metadata support.

pub fn extend_with<F>(&mut self, methods: F)where F: IntoIterator<Item = (String, RemoteProcedure<T>)>,

Extend this MetaIoHandler with methods defined elsewhere.

pub fn handle_request_sync(&self, request: &str, meta: T) -> Option<String>

Handle given request synchronously - will block until response is available. If you have any asynchronous methods in your RPC it is much wiser to use handle_request instead and deal with asynchronous requests in a non-blocking fashion.

pub fn handle_request( &self, request: &str, meta: T ) -> FutureResult<S::Future, S::CallFuture>

Handle given request asynchronously.

pub fn handle_rpc_request( &self, request: Request, meta: T ) -> FutureRpcResult<S::Future, S::CallFuture>

Handle deserialized RPC request.

pub fn handle_call( &self, call: Call, meta: T ) -> Either<S::CallFuture, Either<FutureOutput, Ready<Option<Output>>>>

Handle single call asynchronously.

pub fn iter(&self) -> impl Iterator<Item = (&String, &RemoteProcedure<T>)>

Returns an iterator visiting all methods in arbitrary order.
