A slice is a dynamically sized type representing a 'view' into a sequence of
elements of type
T. The slice type is written as
To use a slice type it generally has to be used behind a pointer for example as:
&[T], a 'shared slice', often just called a 'slice', it doesn't own the data it points to, it borrows it.
&mut [T], a 'mutable slice', mutably borrows the data it points to.
Box<[T]>, a 'boxed slice'
// A heap-allocated array, coerced to a slice let boxed_array: Box<[i32]> = Box::new([1, 2, 3]); // A (shared) slice into an array let slice: &[i32] = &boxed_array[..];
All elements of slices are always initialized, and access to a slice is always bounds-checked in safe methods and operators.
