Struct ObjectIdentity 

pub struct ObjectIdentity { /* private fields */ }

An owning, hashable identity key for an FFI object.

The retained strong reference prevents the allocation address from being reused while the key is alive. This makes it suitable for identity-based maps without exposing raw object pointers to downstream code.

Implementations

impl ObjectIdentity

pub fn of<T: ObjectRefCore>(value: &T) -> Self

Retain the allocation referenced by value as an identity key.

Trait Implementations

impl Clone for ObjectIdentity

fn clone(&self) -> ObjectIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectIdentity

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

Formats the value using the given formatter.

impl Eq for ObjectIdentity

impl Hash for ObjectIdentity

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 ObjectIdentity

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.
