Enum PostAction

pub enum PostAction {
    Continue,
    Reregister,
    Disable,
    Remove,
}

Possible actions that can be requested to the event loop by an event source once its events have been processed.

PostAction values can be combined with the | (bit-or) operator (or with |=) with the result that:

• if both values are identical, the result is that value
• if they are different, the result is Reregister

Bit-or-ing these results is useful for composed sources to combine the results of their child sources, but note that it only applies to the child sources. For example, if every child source returns Continue, the result will be Continue, but the parent source might still need to return Reregister or something else depending on any additional logic it uses.

Variants

Continue

Continue listening for events on this source as before

Reregister

Trigger a re-registration of this source

Disable

Disable this source

Has the same effect as LoopHandle::disable

Remove

Remove this source from the eventloop

Has the same effect as LoopHandle::kill

Trait Implementations

impl BitOr for PostAction

Combines PostAction values returned from nested event sources.

type Output = PostAction

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for PostAction

Combines PostAction values returned from nested event sources.

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for PostAction

fn clone(&self) -> PostAction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PostAction

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

Formats the value using the given formatter.

impl PartialEq for PostAction

fn eq(&self, other: &PostAction) -> 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.
