Request handler

By default compatible only with jsonrpc v2

Methods

impl<T> MetaIoHandler<T, Noop> where     T: Metadata,

[−]

pub fn with_compatibility(     compatibility: Compatibility ) -> MetaIoHandler<T, Noop>

[−]

Creates new MetaIoHandler compatible with specified protocol version.

impl<T, S> MetaIoHandler<T, S> where     S: Middleware<T>,     T: Metadata,

[−]

pub fn new(compatibility: Compatibility, middleware: S) -> MetaIoHandler<T, S>

[−]

Creates new MetaIoHandler

pub fn with_middleware(middleware: S) -> MetaIoHandler<T, S>

[−]

Creates new MetaIoHandler with specified middleware.

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

[−]

Adds an alias to a method.

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: Into<HashMap<String, RemoteProcedure<T>, RandomState>>,

[−]

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 ) -> Map<Either<FutureResult<Option<Response>, ()>, <S as Middleware<T>>::Future>, fn(Option<Response>) -> Option<String>>

[−]

Handle given request asynchronously.

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

[−]

Handle deserialized RPC request.

pub fn handle_call(     &self,     call: Call,     meta: T ) -> Either<Box<Future<Item = Option<Output>, Error = ()> + 'static + Send>, FutureResult<Option<Output>, ()>>

[−]

Handle single call asynchronously.

[+]

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

[−]

Formats the value using the given formatter.

impl From<IoHandler<()>> for MetaIoHandler<(), Noop>

[+]

[−]

Performs the conversion.

impl<T> Default for MetaIoHandler<T, Noop> where     T: Metadata,

[+]

fn default() -> MetaIoHandler<T, Noop>

[−]

Returns the "default value" for a type.

impl<T, S> Into<MetaIoHandler<T, S>> for PubSubHandler<T, S> where     S: Middleware<T>,     T: PubSubMetadata,
