Struct SlotHandle 

pub(super) struct SlotHandle<Tag> {
    index: usize,
    generation: u64,
    _tag: PhantomData<fn() -> Tag>,
}

copy identity for one reusable worker-local slot

callers may queue, copy and compare handles freely because the value is only an access token every read, write or removal must still go through the owning store so stale generations are rejected at the point where state would be touched

Fields

index: usize

generation: u64

_tag: PhantomData<fn() -> Tag>

Trait Implementations

impl<Tag> Clone for SlotHandle<Tag>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Tag: Debug> Debug for SlotHandle<Tag>

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

Formats the value using the given formatter.

impl<Tag> Default for SlotHandle<Tag>

fn default() -> Self

create an invalid handle that cannot match a live generation

impl<Tag: Hash> Hash for SlotHandle<Tag>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<Tag: Ord> Ord for SlotHandle<Tag>

fn cmp(&self, other: &SlotHandle<Tag>) -> 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<Tag: PartialEq> PartialEq for SlotHandle<Tag>

fn eq(&self, other: &SlotHandle<Tag>) -> 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<Tag: PartialOrd> PartialOrd for SlotHandle<Tag>

fn partial_cmp(&self, other: &SlotHandle<Tag>) -> 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.
