Struct Count 

pub(crate) struct Count<K> {
    count: u32,
    marker: PhantomData<K>,
}

A reference count, counting references with id type K

Fields

count: u32

Actual count of references

marker: PhantomData<K>

Bind to the specific key type

Implementations

impl<K> Count<K>

const fn new_raw(count: u32) -> Self

Make a new refcount with a specified value

pub(crate) fn as_usize(&self) -> usize

Obtain this counter as a usize

(Reference counts are u32, so this might be a conversion.)

Methods from Deref<Target = u32>

pub const MIN: u32 = 0

pub const MAX: u32

pub const BITS: u32

Trait Implementations

impl<K> Debug for Count<K>

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

Formats the value using the given formatter.

impl<K: Default> Default for Count<K>

fn default() -> Count<K>

Returns the “default value” for a type.

impl<K> Deref for Count<K>

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<K: Ord> Ord for Count<K>

fn cmp(&self, other: &Count<K>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<K: PartialEq> PartialEq for Count<K>

fn eq(&self, other: &Count<K>) -> 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<K: PartialOrd> PartialOrd for Count<K>

fn partial_cmp(&self, other: &Count<K>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
