Struct EntityId

pub struct EntityId<R = Repo>(/* private fields */);

An index handle to a value in repository.

Implementations

impl<R> EntityId<R>

pub fn cast_repo<R2>(self) -> EntityId<R2>

Convert entity id to work with another repository type.

impl<R: AsRepoRef> EntityId<R>

pub fn cast_ptr<T: Any>(self, repo: &R) -> Option<EntityPtr<T>>

Try to downcast this index handle to a pointer handle.

pub fn cast_ref<T: Any>(self, repo: &R) -> Option<&T>

Try to downcast this index handle to a reference to the value.

impl<R: AsRepoMut> EntityId<R>

pub fn cast_mut<T: Any>(self, repo: &mut R) -> Option<&mut T>

Try to downcast this index handle to a mutable reference to the value.

Trait Implementations

impl<R> Clone for EntityId<R>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R> Debug for EntityId<R>

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

Formats the value using the given formatter.

impl<R> Hash for EntityId<R>

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<R> Ord for EntityId<R>

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<R> PartialEq for EntityId<R>

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<R> PartialOrd for EntityId<R>

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.
