Required Methods

fn ready<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Pollable>, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

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

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

fn block<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Pollable>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

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<(), Error>

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