Expand description
Performs the same functionality as slice_from_raw_parts
, except that a
raw mutable slice is returned, as opposed to a raw immutable slice.
See the documentation of slice_from_raw_parts
for more details.
This function is safe, but actually using the return value is unsafe.
See the documentation of slice::from_raw_parts_mut
for slice safety requirements.
Examples
use std::ptr;
let x = &mut [5, 6, 7];
let raw_pointer = x.as_mut_ptr();
let slice = ptr::slice_from_raw_parts_mut(raw_pointer, 3);
unsafe {
(*slice)[2] = 99; // assign a value at an index in the slice
};
assert_eq!(unsafe { &*slice }[2], 99);
