Enum State 

pub(crate) enum State<T> {
    Created,
    Notified {
        additional: bool,
        tag: T,
    },
    Task(Task),
    NotifiedTaken,
}

The state of a listener.

Variants

Created

The listener was just created.

Notified

The listener has received a notification.

The bool is true if this was an “additional” notification.

Fields

additional: bool

Whether or not this is an “additional” notification.

tag: T

The tag associated with the notification.

Task(Task)

A task is waiting for a notification.

NotifiedTaken

Empty hole used to replace a notified listener.

Implementations

impl<T> State<T>

pub(crate) fn is_notified(&self) -> bool

pub(crate) fn notified(self) -> Option<T>

If this state was notified, return the tag associated with the notification.

Trait Implementations

impl<T> Debug for State<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for State<T>

fn eq(&self, other: &State<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
