Trait HostPollable

pub trait HostPollable: Send {
    // Required methods
    fn ready(
        &mut self,
        self_: Resource<Pollable>,
    ) -> impl Future<Output = Result<bool>> + Send;
    fn block(
        &mut self,
        self_: Resource<Pollable>,
    ) -> impl Future<Output = Result<()>> + Send;
    fn drop(&mut self, rep: Resource<Pollable>) -> Result<()>;
}

Required Methods

fn ready( &mut self, self_: Resource<Pollable>, ) -> impl Future<Output = Result<bool>> + Send

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

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

fn block( &mut self, self_: Resource<Pollable>, ) -> impl Future<Output = Result<()>> + Send

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.

fn drop(&mut self, rep: Resource<Pollable>) -> Result<()>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<_T: HostPollable + ?Sized + Send> HostPollable for &mut _T

async fn ready(&mut self, self_: Resource<Pollable>) -> Result<bool>

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

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

async fn block(&mut self, self_: Resource<Pollable>) -> Result<()>

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.

fn drop(&mut self, rep: Resource<Pollable>) -> Result<()>
