Struct rustix::event::epoll::EventVec

pub struct EventVec { /* private fields */ }

A vector of Events, plus context for interpreting them.

Implementations

impl EventVec

pub unsafe fn from_raw_parts( ptr: *mut Event, len: usize, capacity: usize ) -> Self

Constructs an EventVec from raw pointer, length, and capacity.

Safety

This function calls Vec::from_raw_parts with its arguments.

pub fn with_capacity(capacity: usize) -> Self

Constructs an EventVec with memory for capacity Events.

pub fn capacity(&self) -> usize

Returns the current Event capacity of this EventVec.

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

Reserves enough memory for at least additional more Events.

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

Reserves enough memory for exactly additional more Events.

pub fn clear(&mut self)

Clears all the Events out of this EventVec.

pub fn shrink_to_fit(&mut self)

Shrinks the capacity of this EventVec as much as possible.

pub fn iter(&self) -> Iter<'_>

Returns an iterator over the Events in this EventVec.

pub fn len(&mut self) -> usize

Returns the number of Events logically contained in this EventVec.

pub fn is_empty(&mut self) -> bool

Tests whether this EventVec is logically empty.

Trait Implementations

impl<'a> IntoIterator for &'a EventVec

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

type Item = Event

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
