Struct RawSlice

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

Implementations

impl<T> RawSlice<T>

pub const unsafe fn new(data: &[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: &[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 fn set_null(&mut self)

Set the internal data pointer to NULL and also clears the data length.

pub const fn is_null(&self) -> bool

Check whether the internal data pointer is NULL.

pub const unsafe fn get(&self) -> Option<&[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 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 RawSlice<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for RawSlice<T>

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

Formats the value using the given formatter.

impl<T> Default for RawSlice<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for RawSlice<T>

fn eq(&self, other: &RawSlice<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Copy> Copy for RawSlice<T>

impl<T: Eq> Eq for RawSlice<T>

impl<T: Send> Send for RawSlice<T>

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