Struct FlagListener 

pub struct FlagListener { /* private fields */ }

Flag::listener() implementation.

Trait Implementations

impl Clone for FlagListener

fn clone(&self) -> FlagListener

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlagListener

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

Formats the value using the given formatter.

impl<M> FromListener<FlagListener, M> for FlagListener

fn from_listener(listener: FlagListener) -> Self

No-op conversion returning the listener unchanged.

impl<M> Listener<M> for FlagListener

fn receive(&self, messages: &[M]) -> bool

Process and store the given series of messages.

fn filter<MI, F>(self, function: F) -> Filter<F, Self, 1>

where Self: Sized, F: for<'a> Fn(&'a MI) -> Option<M>,

Wraps self so to apply a map/filter function (similar to Iterator::filter_map()) to incoming messages, to discard uninteresting messages and transform interesting ones.

fn gate(self) -> (Gate, GateListener<Self>)

where Self: Sized,

Wraps self to pass messages only until the returned Gate, and any clones of it, are dropped.

impl Pointer for FlagListener

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

Produces an address which is the same for this FlagListener and its associated Flag.
