Struct std::sync::mpsc::SelectUnstable
[-] [+]
[src]
pub struct Select {
// some fields omitted
}The "receiver set" of the select interface. This structure is used to manage a set of receivers which are being selected over.
Methods
impl Select
fn new() -> Select
Creates a new selection structure. This set is initially empty.
Usage of this struct directly can sometimes be burdensome, and usage is much easier through
the select! macro.
Examples
fn main() { use std::sync::mpsc::Select; let select = Select::new(); }use std::sync::mpsc::Select; let select = Select::new();
fn handle<'a, T: Send + 'static>(&'a self, rx: &'a Receiver<T>) -> Handle<'a, T>
Creates a new handle into this receiver set for a new receiver. Note
that this does not add the receiver to the receiver set, for that you
must call the add method on the handle itself.
fn wait(&self) -> usize
Waits for an event on this receiver set. The returned value is not an
index, but rather an id. This id can be queried against any active
Handle structures (each one has an id method). The handle with
the matching id will have some sort of event available on it. The
event could either be that data is available or the corresponding
channel has been closed.
