Struct RawSliceMut 

pub struct RawSliceMut<T> { /* private fields */ }

Implementations

impl<T> RawSliceMut<T>

pub const unsafe fn new(data: &mut [T]) -> Self

Creates a new RawSlice<T> from a slice reference.

Safety

• The caller must ensure that the slice outlives this RawSlice<T>.
• The original slice must not be mutated while this RawSlice<T> is used.

pub const fn new_nulled() -> Self

Creates an empty RawSlice<T>, equivalent to a null pointer with zero length.

pub const unsafe fn set(&mut self, data: &mut [T])

Updates the raw pointer and length to point to a new slice.

Safety

• The caller must ensure that the slice outlives this RawSlice<T>.
• The original slice must not be mutated while this RawSlice<T> is used.

pub const unsafe fn get<'slice>(&self) -> Option<&'slice [T]>

Converts the raw pointer into a slice.

Returns None if the pointer is null.

Safety

• The caller must ensure that the underlying memory is still valid.
• Using this function after the original slice is dropped results in UB.

pub const unsafe fn get_mut<'slice>(&mut self) -> Option<&'slice mut [T]>

Converts the raw pointer into a mutable slice.

Returns None if the pointer is null.

Safety

• The caller must ensure that the underlying memory is still valid.
• Using this function after the original slice is dropped results in UB.

pub const fn set_null(&mut self)

pub const fn is_null(&self) -> bool

pub const fn is_empty(&self) -> Option<bool>

Returns None if the pointer is null and whether Self::len is 0 otherwise.

pub const fn len(&self) -> Option<usize>

Returns None if the pointer is null and the length of the raw slice otherwise.

Trait Implementations

impl<T: Clone> Clone for RawSliceMut<T>

fn clone(&self) -> RawSliceMut<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for RawSliceMut<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for RawSliceMut<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Copy> Copy for RawSliceMut<T>

impl<T: Send> Send for RawSliceMut<T>

Safety: This type MUST be used with mutex to ensure concurrent access is valid.
