Struct StdAllocator 

#[repr(C)]
pub struct StdAllocator;

Available on crate feature std only.

The standard allocator based on alloc crate.

Trait Implementations

impl Allocator for StdAllocator

type SpecificAllocationError = StdAllocationError

A specific Allocator error. Implementor can add additional information to the error, not only generic “allocation failed”.

fn allocate( &mut self, layout: Layout, ) -> Result<NonNull<u8>, Self::SpecificAllocationError>

Allocates new piece of memory. This is the only safe function here. The returned ptr is guaranteed to satisfy layout requirements (although the implementation is free to overallocate and strengthen alignment).

unsafe fn deallocate(&mut self, ptr: NonNull<u8>, layout: Layout)

Deallocates memory.

unsafe fn resize( &mut self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<u8>, Self::SpecificAllocationError>

Resizes given ptr to the new layout.

impl Clone for StdAllocator

fn clone(&self) -> StdAllocator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StdAllocator

impl Debug for StdAllocator

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

Formats the value using the given formatter.

impl Default for StdAllocator

fn default() -> StdAllocator

Returns the “default value” for a type.

impl Eq for StdAllocator

impl PartialEq for StdAllocator

fn eq(&self, other: &StdAllocator) -> 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 ReprC for StdAllocator

const CHECK: () = ()

This field is used for const checks only.

impl StructuralPartialEq for StdAllocator

impl TryClone for StdAllocator

type Error = Infallible

fn try_clone(&self) -> Result<Self, Self::Error>

Tries to clone the type.
