Struct ReadMessageState 

pub struct ReadMessageState { /* private fields */ }

An object for managing the state of an async channel read message operation that can be used to implement futures.

Implementations

impl ReadMessageState

pub unsafe fn register_read_wait<T: ?Sized>(channel: &mut Channel<T>) -> Self

Creates a new raw read message state that can be used to implement a Future that reads data from a channel and then converts it to the appropriate type. It also allows for different ways of storing and managing the dispatcher we wait on by deferring the dispatcher used to poll time. This state is registered with the given Channel so that dropping the channel will correctly free resources.

Safety

The caller is responsible for ensuring that the handle inside channel outlives this object.

pub fn poll_with_dispatcher<D: OnDispatcher>( &mut self, cx: &mut Context<'_>, dispatcher: D, ) -> Poll<Result<Option<Message<[MaybeUninit<u8>]>>, Status>>

Polls this channel read operation against the given dispatcher.
