Struct Permit 

pub struct Permit<'a, T> { /* private fields */ }

Room for one message, reserved before the message exists.

The send through it never waits and never fails, even when the receiver was closed in the meantime. Dropping it without sending gives the slot back.

use nuclei::sync::local::mpsc;

let (tx, mut rx) = mpsc::channel(1);
let permit = tx.try_reserve().unwrap();
permit.send("reserved");
assert_eq!(rx.try_recv(), Ok("reserved"));

Implementations

impl<T> Permit<'_, T>

pub fn send(self, value: T)

Sends a value through the reserved slot, consuming the permit.

Trait Implementations

impl<T> Debug for Permit<'_, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Drop for Permit<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
