Struct ActionQueue 

pub struct ActionQueue<A: UiAction> { /* private fields */ }

The drain side of an action queue: the same buffer as its Sink.

Implementations

impl<A: UiAction> ActionQueue<A>

pub fn new() -> Self

pub fn pair() -> (Self, Sink<A>)

A fresh queue and the sink for the view that pushes into it.

pub fn sink(&self) -> Sink<A>

The push handle. Cloning it into every control is the intended use.

pub fn push(&self, action: A)

Queue one action from the drain side.

pub fn pending(&self) -> usize

Actions waiting to be drained.

pub fn is_empty(&self) -> bool

pub fn drain(&self) -> Vec<A>

Take everything queued before this call, in push order.

pub fn drain_into(&self, out: &mut Vec<A>)

Take everything queued before this call, appending to out.

pub fn absorb(&self, intents: &mut Intents<A>) -> usize

Drain into an intent buffer. Returns how many actions were absorbed.

Trait Implementations

impl<A: Clone + UiAction> Clone for ActionQueue<A>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: UiAction> Debug for ActionQueue<A>

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

Formats the value using the given formatter.

impl<A: UiAction> Default for ActionQueue<A>

fn default() -> Self

Returns the “default value” for a type.
