Struct mini_io_queue::RegionMut

pub struct RegionMut<'a, T>(_, _);

A region of two separate mutable slices that represent continuous data.

This is the mutable equivalent to Region, allowing mutable access to the contained slices.

Implementations

impl<'a, T> RegionMut<'a, T>

pub fn new(slice_0: &'a mut [T], slice_1: &'a mut [T]) -> Self

Creates a region with two mutable slices.

The slices should represent continuous data, where slice_0 goes before slice_1.

pub fn as_ref(&self) -> Region<'_, T>

Returns a non-mutable version of the region.

pub fn is_empty(&self) -> bool

Returns true if the region has a length of 0.

pub fn len(&self) -> usize

Returns the number of elements in the region.

pub fn iter(&self) -> impl Iterator<Item = &T>

Returns an iterator over the region.

The iterator yields all items from start to end.

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut T>

Returns an iterator that allows modifying each value.

The iterator yields all items from start to end.

pub fn contiguous(&self) -> &[T]

Returns the first contiguous slice in the region.

The slice will not necessarily contain all data in the region.

pub fn contiguous_mut(&mut self) -> &mut [T]

Returns a mutable reference to the first contiguous slice in the region.

The slice will not necessarily contain all data in the region.

pub fn slice<R>(&self, range: R) -> Region<'_, T> where
    R: RangeBounds<usize>, 

Slices the region, returning a new region containing a part of the original.

Panics

Panics if the start or end of the range is >= region.len().

pub fn slice_mut<R>(&mut self, range: R) -> RegionMut<'_, T> where
    R: RangeBounds<usize>, 

Slices the region, returning a new mutable region containing a part of the original.

Panics

Panics if the start or end of the range is >= region.len().

impl<'a, T> RegionMut<'a, T> where
    T: Copy, 

pub fn copy_to_slice(&self, slice: &mut [T])

Copies all elements in the region into dest, using a memcpy.

The length of dest must be the same as self.

If T does not implement Copy, use clone_to_slice.

Panics

This function will panic if dest has a different length to self.

pub fn copy_from_slice(&mut self, src: &[T])

Copies all elements from src into the region, using a memcpy.

The length of src must be the same as self.

If T does not implement Copy, use clone_from_slice.

Panics

This function will panic if src has a different length to self.

impl<'a, T> RegionMut<'a, T> where
    T: Clone, 

pub fn clone_to_slice(&self, slice: &mut [T])

Copies all elements in the region into dest.

The length of dest must be the same as self.

Panics

This function will panic if dest has a different length to self.

pub fn clone_from_slice(&mut self, src: &[T])

Copies all elements from src into the region.

The length of src must be the same as self.

Panics

This function will panic if src has a different length to self.

Trait Implementations

impl<'a, T> Default for RegionMut<'a, T>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, T: Hash> Hash for RegionMut<'a, T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<'a, T> Index<usize> for RegionMut<'a, T>

type Output = T

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a, T> IndexMut<usize> for RegionMut<'a, T>

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<'a, T: PartialEq> PartialEq<RegionMut<'a, T>> for RegionMut<'a, T>

fn eq(&self, other: &RegionMut<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
