Struct MutPtrByteSlice 

pub struct MutPtrByteSlice<'a> { /* private fields */ }

A mutable view of a raw pointer byte slice, providing a safe API.

Implementations

impl<'a> MutPtrByteSlice<'a>

pub unsafe fn new(slice: *mut [u8]) -> Self

Creates a new MutPtrByteSlice from a raw mutable pointer to a byte slice.

Safety

The caller must ensure that slice is valid for reads and writes for the lifetime 'a.

pub fn len(&self) -> usize

Returns the length of the slice in bytes.

pub fn is_empty(&self) -> bool

Returns true if the slice has a length of 0.

pub fn copy_to_slice(&self, dest: &mut [u8])

Copies the contents of this slice into a safe Rust mutable slice.

Panics

Panics if dest is smaller than self.len().

pub fn copy_from_ptr_slice(&mut self, src: PtrByteSlice<'_>)

Copies the contents of another read-only pointer slice into this mutable slice.

Panics

Panics if the lengths of the slices do not match.

pub fn fill(&mut self, val: u8)

Fills the slice with the given byte value.

pub fn as_ptr_slice(&self) -> PtrByteSlice<'_>

Returns a read-only view of this slice.

pub fn subslice_mut(&mut self, range: Range<usize>) -> Self

Returns a mutable subslice of this pointer slice.

Panics

Panics if the range is out of bounds.

pub fn split_at_mut(self, mid: usize) -> (Self, Self)

Splits the slice into two at the given index.

Panics

Panics if mid is out of bounds.

pub fn as_ptr(&self) -> *const u8

Returns a raw pointer to the start of the slice.

pub fn as_mut_ptr(&self) -> *mut u8

Returns a raw mutable pointer to the start of the slice.

pub fn reborrow(&mut self) -> MutPtrByteSlice<'_>

Reborrows the mutable slice with a shorter lifetime.

pub fn to_vec(&self) -> Vec<u8>

Allocates a new heap Vector and copies the contents into it. Bypasses zero-initialization using raw pointer copies.

pub fn append_to(&self, vec: &mut Vec<u8>)

Appends the contents of this slice to the given vector, expanding its capacity if needed. Bypasses zero-initialization using raw pointer copies.

pub fn chunks_mut<T: Copy + FromBytes>(&mut self) -> ChunksMut<'_, T>

Returns an iterator over mutable chunks of type T.

Panics

Panics if the slice is not aligned to T or if its length in bytes is not a multiple of size_of::<T>().
