Struct bevy_internal::ecs::event::EventId

pub struct EventId<E>
where
    E: Event,
{
    pub id: usize,
    /* private fields */
}

An EventId uniquely identifies an event stored in a specific World.

An EventId can among other things be used to trace the flow of an event from the point it was sent to the point it was processed.

Fields

id: usize

Uniquely identifies the event associated with this ID.

Trait Implementations

impl<E> Clone for EventId<E>

where E: Event,

fn clone(&self) -> EventId<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E> Debug for EventId<E>

where E: Event,

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

Formats the value using the given formatter.

impl<E> Display for EventId<E>

where E: Event,

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

Formats the value using the given formatter.

impl<E> Hash for EventId<E>

where E: Event,

fn hash<H>(&self, state: &mut H)

where H: Hasher,

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<E> Ord for EventId<E>

where E: Event,

fn cmp(&self, other: &EventId<E>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<E> PartialEq for EventId<E>

where E: Event,

fn eq(&self, other: &EventId<E>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<E> PartialOrd for EventId<E>

where E: Event,

fn partial_cmp(&self, other: &EventId<E>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<E> Copy for EventId<E>

where E: Event,

impl<E> Eq for EventId<E>

where E: Event,
