sourcepub fn each_ref(&self) -> [&T; N]
🔬 This is a nightly-only experimental API. (array_methods
)
pub fn each_ref(&self) -> [&T; N]
array_methods
)Borrows each element and returns an array of references with the same
size as self
.
Example
#![feature(array_methods)]
let floats = [3.1, 2.7, -1.0];
let float_refs: [&f64; 3] = floats.each_ref();
assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);
This method is particularly useful if combined with other methods, like
map
. This way, you can avoid moving the original
array if its elements are not Copy
.
#![feature(array_methods)]
let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()];
let is_ascii = strings.each_ref().map(|s| s.is_ascii());
assert_eq!(is_ascii, [true, false, true]);
// We can still access the original array: it has not been moved.
assert_eq!(strings.len(), 3);
sourcepub fn each_mut(&mut self) -> [&mut T; N]
🔬 This is a nightly-only experimental API. (array_methods
)
pub fn each_mut(&mut self) -> [&mut T; N]
array_methods
)Borrows each element mutably and returns an array of mutable references
with the same size as self
.
Example
#![feature(array_methods)]
let mut floats = [3.1, 2.7, -1.0];
let float_refs: [&mut f64; 3] = floats.each_mut();
*float_refs[0] = 0.0;
assert_eq!(float_refs, [&mut 0.0, &mut 2.7, &mut -1.0]);
assert_eq!(floats, [0.0, 2.7, -1.0]);
sourcepub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])
🔬 This is a nightly-only experimental API. (split_array
)
pub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])
split_array
)Divides one array reference into two at an index.
The first will contain all indices from [0, M)
(excluding
the index M
itself) and the second will contain all
indices from [M, N)
(excluding the index N
itself).
Panics
Panics if M > N

sourcepub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])
🔬 This is a nightly-only experimental API. (split_array
)
pub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])
split_array
)Divides one array reference into two at an index from the end.
