Trait HostPollable

pub trait HostPollable: Sized {
    // Required methods
    fn ready(&mut self, self_: Resource<DynPollable>) -> Result<bool, Error>;
    fn block(&mut self, self_: Resource<DynPollable>) -> Result<(), Error>;
    fn drop(&mut self, rep: Resource<DynPollable>) -> Result<(), Error>;
}

Required Methods

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

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<DynPollable>) -> Result<(), Error>

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<DynPollable>) -> Result<(), Error>

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.
