pub struct ErasedStreamHandler(/* private fields */);
Expand description

Type-erased streaming handler — same principle as ErasedHandler (see #58).

Implementations§

Source§

impl ErasedStreamHandler

Source

pub fn from_closure(f: Box<StreamHandlerCallFn>) -> Self

Create an ErasedStreamHandler from an already-boxed closure.

Non-generic counterpart to the convenience constructors. Used by the erase_streaming_handler! macros.

Source

pub fn no_args<F, Fut, R>(handler: F) -> Self
where F: Fn(StreamSender) -> Fut + Send + Sync + 'static, Fut: Future<Output = R> + Send + 'static, R: IntoHandlerResult + 'static,

Erase a streaming handler with no args.

Source

pub fn with_args<F, T, Fut, R>(handler: F) -> Self
where F: Fn(T, StreamSender) -> Fut + Send + Sync + 'static, T: DeserializeOwned + Send + 'static, Fut: Future<Output = R> + Send + 'static, R: IntoHandlerResult + 'static,

Erase a streaming handler with typed args.

Source

pub fn with_state<F, S, T, Fut, R>(handler: F, states: SharedStateMap) -> Self
where F: Fn(State<Arc<S>>, T, StreamSender) -> Fut + Send + Sync + 'static, S: Send + Sync + 'static, T: DeserializeOwned + Send + 'static, Fut: Future<Output = R> + Send + 'static, R: IntoHandlerResult + 'static,

Erase a streaming handler with state + typed args.

Source

pub fn with_state_only<F, S, Fut, R>(handler: F, states: SharedStateMap) -> Self
where F: Fn(State<Arc<S>>, StreamSender) -> Fut + Send + Sync + 'static, S: Send + Sync + 'static, Fut: Future<Output = R> + Send + 'static, R: IntoHandlerResult + 'static,

Erase a streaming handler with state only (no args).
