Struct Handle

pub struct Handle<T>
where
    T: Handled + ?Sized,
{
    pub core: T::HandleCoreType,
}

A lightweight identifier for instances of an arbitrary type T.

Fields

core: T::HandleCoreType

The internal representation of the identifier.

Implementations

impl<T> Handle<T>

where T: Handled + ?Sized,

pub fn mock(existing_handles: &Vec<Handle<T>>) -> Handle<T>

Creates a handle different from all handles in a given list of existing_handles.

This may serve as “a handle to nothing”, a “mock handle”.

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

Feeds this value into the given Hasher.

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

impl<T> Into<usize> for Handle<T>

where T: Handled + ?Sized,

fn into(self) -> usize

Converts a handle to the serial number it identifies.

impl<T> Ord for Handle<T>

where T: OrderlyHandled,

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

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

impl<T> PartialEq for Handle<T>

where T: Handled + ?Sized,

fn eq(&self, __other: &Self) -> 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<T> PartialOrd for Handle<T>

where T: OrderlyHandled,

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

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

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

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.
