Struct Select 

pub struct Select;

Non-blocking poll over multiple receive closures.

This is a single-pass poll, not a Go-style blocking select: each closure is tried once in order and the first successful receive wins; when every closure fails the call returns None immediately without waiting or registering wakeups.

Implementations

impl Select

pub fn try_recv<T>( receivers: &mut [&mut dyn FnMut() -> Result<T, ChannelError>], ) -> Option<(usize, T)>

Poll each receiver closure once in order, returning the first available value with its index, or None if none is ready.
