Struct cl_generic_vec::raw::ZeroSized

pub struct ZeroSized<T>(_);

A storage that can hold zero sized types

Implementations

impl<T> ZeroSized<T>

pub const NEW: Self

Create a new zero-sized allocator, can only be used with zero-sized types

let _ = ZeroSized::<[i32; 0]>::NEW;

let _ = ZeroSized::<u8>::NEW;

pub const TRY_NEW: Option<Self>

Try to create a new zero-sized allocator, will be None if the type is not zero sized

assert!(ZeroSized::<[i32; 0]>::TRY_NEW.is_some());
assert!(ZeroSized::<u8>::TRY_NEW.is_none());

Trait Implementations

impl<T> Clone for ZeroSized<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Default for ZeroSized<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Storage<T> for ZeroSized<T>

const IS_ALIGNED: bool

Is the pointer from as_ptr guaranteed to be aligned to T

fn as_ptr(&self) -> *const T

Returns a pointer to the first element

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

Returns a mutable pointer to the first element

fn reserve(&mut self, _: usize)
