Trait Implementations

impl CallbackRef for Counter

fn alloc(
    &self,
    _layout: Layout,
    _init: AllocInit,
    _result: Result<MemoryBlock, AllocErr>
)

Called when [alloc] was invoked.

fn dealloc(&self, _ptr: NonNull<u8>, _layout: Layout)

Called when [dealloc] was invoked.

fn grow(
    &self,
    _ptr: NonNull<u8>,
    _layout: Layout,
    _new_size: usize,
    _placement: ReallocPlacement,
    _init: AllocInit,
    _result: Result<MemoryBlock, AllocErr>
)

Called when [grow] was invoked.

fn shrink(
    &self,
    _ptr: NonNull<u8>,
    _layout: Layout,
    _new_size: usize,
    _placement: ReallocPlacement,
    _result: Result<MemoryBlock, AllocErr>
)

Called when [shrink] was invoked.

fn owns(&self, _success: bool)

Called when [owns] was invoked.

fn by_ref(&self) -> &Self

Creates a "by reference" adaptor for this instance of CallbackRef.

impl Debug for Counter

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

Formats the value using the given formatter.

impl Default for Counter

fn default() -> Counter

Returns the "default value" for a type.

impl Eq for Counter

impl PartialEq<AtomicCounter> for Counter

fn eq(&self, other: &AtomicCounter) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialEq<Counter> for Counter

fn eq(&self, other: &Counter) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialEq<Counter> for AtomicCounter

fn eq(&self, other: &Counter) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
