Names used in signatures

Unqualified names denote this package’s types (including other source files in the same package), language built-ins, or generic parameters such as T. Qualified names use the import aliases below. These aliases belong to the library source; import a dependency yourself to use its alias in your program.

SplitMut

Struct · Source

Compiler-recognized pair: only split_at_mut constructs it, and individual slice descriptors cannot be replaced. Consume it with let slice.SplitMut{left, right} = parts for independent exclusive views. The fields do not own T.

pub struct SplitMut<T> {
    pub &mut[T] left
    pub &mut[T] right
}

split_at_mut

Function · Source

Checked like subslice_mut: both boundary splits succeed; an invalid midpoint returns none. The source stays borrowed until both views expire.

pub fn split_at_mut<T>(data: &mut[T], mid: usize) -> Option<SplitMut<T>> from(data)

is_empty

Function · Source

Optional checked access. Returned views retain the source borrow.

pub fn is_empty<T>(data: &[T]) -> bool

get

Function · Source

pub fn get<T>(data: &[T], index: usize) -> Option<&T> from(data)

get_mut

Function · Source

pub fn get_mut<T>(data: &mut[T], index: usize) -> Option<&mut T> from(data)

first

Function · Source

pub fn first<T>(data: &[T]) -> Option<&T> from(data)

last

Function · Source

pub fn last<T>(data: &[T]) -> Option<&T> from(data)

subslice

Function · Source

pub fn subslice<T>(data: &[T], start: usize, end: usize) -> Option<&[T]> from(data)

subslice_mut

Function · Source

pub fn subslice_mut<T>(data: &mut[T], start: usize, end: usize) -> Option<&mut[T]> from(data)
