Struct Handle 

pub struct Handle<T> { /* private fields */ }

A stable handle to allocated memory.

Handles remain valid across relocations. The actual pointer is resolved at access time.

Implementations

impl<T> Handle<T>

pub const fn dangling() -> Self

Create a dangling handle (for default initialization).

pub fn is_dangling(&self) -> bool

Check if this is a dangling/invalid handle.

pub fn raw_index(&self) -> u32

Get the raw index (for debugging).

pub fn raw_generation(&self) -> u32

Get the generation (for debugging).

Trait Implementations

impl<T> Clone for Handle<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Handle<T>

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

Formats the value using the given formatter.

impl<T> Default for Handle<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Hash for Handle<T>

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<T> PartialEq for Handle<T>

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.
