Struct wasmcloud_runtime::capability::wrpc::wasi::io::poll::Pollable

pub struct Pollable(/* private fields */);

pollable represents a single I/O event which may be ready, or not.

Implementations

impl Pollable

pub fn ready<'a, C: Invoke>( wrpc__: &'a C, cx__: C::Context, self_: &'a ResourceBorrow<Pollable>, ) -> impl Future<Output = Result<bool>> + Send + 'a

Return the readiness of a pollable. This function never blocks.

Returns true when the pollable is ready, and false otherwise.

impl Pollable

pub fn block<'a, C: Invoke>( wrpc__: &'a C, cx__: C::Context, self_: &'a ResourceBorrow<Pollable>, ) -> impl Future<Output = Result<()>> + Send + 'a

block returns immediately if the pollable is ready, and otherwise blocks until ready.

This function is equivalent to calling poll.poll on a list containing only this pollable.
