Slice types
Syntax
SliceType :
[
Type]
A slice is a dynamically sized type representing a ‘view’ into a sequence of
elements of type T
. The slice type is written as [T]
.
Slice types are generally used through pointer types. For example:
&[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’. It mutably borrows the data it points to.Box<[T]>
: a ‘boxed slice’
Examples:
All elements of slices are always initialized, and access to a slice is always bounds-checked in safe methods and operators.
