Required Methods§

source

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.

source

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.

source

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