source · [−]

    pub struct EventVec<'context, Context: Context> { /* private fields */ }

Expand description

A vector of `Event`s, plus context for interpreting them.

## Implementations

source

### impl<'context, Context: Context> EventVec<'context, Context>

source

#### pub fn with_capacity(capacity: usize) -> Self

Constructs an `EventVec` with memory for `capacity` `Event`s.

source

#### pub fn capacity(&self) -> usize

Returns the current `Event` capacity of this `EventVec`.

source

#### pub fn reserve(&mut self, additional: usize)

Reserves enough memory for at least `additional` more `Event`s.

source

#### pub fn reserve_exact(&mut self, additional: usize)

Reserves enough memory for exactly `additional` more `Event`s.

source

#### pub fn clear(&mut self)

Clears all the `Events` out of this `EventVec`.

source

#### pub fn shrink_to_fit(&mut self)

Shrinks the capacity of this `EventVec` as much as possible.

source

#### pub fn iter(&self) -> Iter<'_, Context>ⓘNotable traits for Iter<'context, Context>`impl<'context, Context: Context> Iterator for Iter<'context, Context> type Item = (EventFlags, Ref<'context, Context::Target>);`

Returns an iterator over the `Event`s in this `EventVec`.

source

#### pub fn len(&mut self) -> usize

Returns the number of `Event`s logically contained in this `EventVec`.

source

#### pub fn is_empty(&mut self) -> bool

Tests whether this `EventVec` is logically empty.
