Struct Handle 

pub struct Handle { /* private fields */ }

Generation-checked identity of one allocation. It stops resolving as soon as its allocation is freed, even if the slot is reused for another run.

Implementations

impl Handle

pub const NONE: Handle

A handle that is never current, for filling buffers.

pub const fn pool(self) -> u8

Pool number the handle was allocated from.

pub const fn slot(self) -> u16

Allocation slot inside that pool.

pub const fn generation(self) -> u32

Generation of the slot when the handle was issued.

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl Hash for 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)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl PartialEq for Handle

fn eq(&self, other: &Handle) -> 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.
