[−][src]Trait array_ops::ArrayMut
Trait for arrays with mutable indexes.
Provided methods
fn get_mut(&mut self, index: usize) -> Option<&mut Self::Output>
Get a mutable reference to the element at the given index.
fn first_mut(&mut self) -> Option<&mut Self::Output>
Get a mutable reference to the first element in the array.
fn last_mut(&mut self) -> Option<&mut Self::Output>
Get a mutable reference to the last element in the array.
fn set(&mut self, index: usize, value: Self::Output) -> Option<Self::Output> where
Self::Output: Sized,
Self::Output: Sized,
Set the value of the element at the given index.
Returns the previous value, or None
if the index is out of bounds.
fn swap(&mut self, index1: usize, index2: usize) where
Self::Output: Sized,
Self::Output: Sized,
Swap the elements at two indexes.
fn map_pair<F, A>(&mut self, index1: usize, index2: usize, f: F) -> A where
F: FnMut(&mut Self::Output, &mut Self::Output) -> A,
F: FnMut(&mut Self::Output, &mut Self::Output) -> A,
Get mutable references to the elements at two indexes and call a function on them.
This provides a safe way to get two mutable references into an array at the same time, which would normally be disallowed by the borrow checker.
fn sort_unstable(&mut self) where
Self::Output: Ord + Sized,
Self::Output: Ord + Sized,
Sort the elements of the array.
fn sort_unstable_by<F>(&mut self, compare: F) where
Self::Output: Sized,
F: FnMut(&Self::Output, &Self::Output) -> Ordering,
Self::Output: Sized,
F: FnMut(&Self::Output, &Self::Output) -> Ordering,
Sort the elements of the array using a comparator function.
fn sort_unstable_by_key<F, K>(&mut self, extract: F) where
F: FnMut(&Self::Output) -> K,
K: Ord,
Self::Output: Sized,
F: FnMut(&Self::Output) -> K,
K: Ord,
Self::Output: Sized,
Sort the elements of the array using a key extractor function.
