Struct RawSliceMut

#[repr(C)]
pub struct RawSliceMut<T> { /* private fields */ }

A C complitable mutable slice of type T

Implementations

impl<T> RawSliceMut<T>

pub unsafe fn from_raw_parts(ptr: *mut T, len: usize) -> RawSliceMut<T>

pub fn len(&self) -> usize

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

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

pub unsafe fn into_slice_mut<'a>(self) -> Option<&'a mut [T]>

Converts a RawSliceMut<T> into a slice of type T

returns None if the slice ptr is null or the length is zero

Safety

panics if the slice ptr is not aligned to the alignment of T

impl<T> RawSliceMut<RawSlice<T>>

pub unsafe fn from_slices(slices: *mut [&[T]]) -> RawSliceMut<RawSlice<T>>

Converts a slice of slices of [T] into RawSliceMut<RawSlice<T>>

Safety

slices becomes invalid after use as it is going to be reused as a memory location for creating Self making this unexpensive but dangerous O(N) expect if the Layout of RawSlice is equal to the Layout of rust slices, and it has been optimized it is O(1)
