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>,

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>, ) -> impl Future<Output = Result<()>> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
