Struct s_jsonrpc_core::MetaIoHandler

pub struct MetaIoHandler<T: Metadata, S: Middleware<T> = Noop> { /* fields omitted */ }

Request handler

By default compatible only with jsonrpc v2

Methods

impl<T: Metadata> MetaIoHandler<T>

pub fn with_compatibility(compatibility: Compatibility) -> Self

Creates new MetaIoHandler compatible with specified protocol version.

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

pub fn new(compatibility: Compatibility, middleware: S) -> Self

Creates new MetaIoHandler

pub fn with_middleware(middleware: S) -> Self

Creates new MetaIoHandler with specified middleware.

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

Adds an alias to a msod.

pub fn add_msod<F>(&mut self, name: &str, msod: F) where
    F: RpcMsodSimple, 

Adds new supported asynchronous msod

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

Adds new supported notification

pub fn add_msod_with_meta<F>(&mut self, name: &str, msod: F) where
    F: RpcMsod<T>, 

Adds new supported asynchronous msod 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, msods: F) where
    F: Into<HashMap<String, RemoteProcedure<T>>>, 

Extend this MetaIoHandler with msods 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 msods 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>

Handle given request asynchronously.

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

Handle deserialized RPC request.

pub fn handle_call(
    &self,
    call: Call,
    meta: T
) -> Either<Box<dyn Future<Item = Option<Output>, Error = ()> + Send>, FutureResult<Option<Output>, ()>>

Handle single call asynchronously.
