Struct AnyWeakEntity 

pub struct AnyWeakEntity { /* private fields */ }

A type erased, weak reference to a entity.

Implementations

impl AnyWeakEntity

pub fn entity_id(&self) -> EntityId

Get the entity ID associated with this weak reference.

pub fn is_upgradable(&self) -> bool

Check if this weak handle can be upgraded, or if the entity has already been dropped

pub fn upgrade(&self) -> Option<AnyEntity>

Upgrade this weak entity reference to a strong reference.

pub fn new_invalid() -> Self

Creates a weak entity that can never be upgraded.

Trait Implementations

impl Clone for AnyWeakEntity

fn clone(&self) -> AnyWeakEntity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnyWeakEntity

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

Formats the value using the given formatter.

impl<T> From<WeakEntity<T>> for AnyWeakEntity

fn from(entity: WeakEntity<T>) -> Self

Converts to this type from the input type.

impl Hash for AnyWeakEntity

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 Ord for AnyWeakEntity

fn cmp(&self, other: &Self) -> 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 PartialEq for AnyWeakEntity

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 PartialOrd for AnyWeakEntity

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

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.
