Struct Spawn

#[repr(transparent)]
pub struct Spawn(pub EntityId);

A GlobalEvent which signals the creation of an entity. Contains the EntityId of the new entity, which may or may not exist by the time this event is observed.

Note that the event by itself cannot be used to spawn new entities. Use World::spawn or Sender::spawn instead.

Tuple Fields

0: EntityId

Trait Implementations

impl Clone for Spawn

fn clone(&self) -> Spawn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Spawn

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

Formats the value using the given formatter.

impl Event for Spawn

type This<'a> = Spawn

The type of Self, but with lifetimes modified to outlive 'a.

type EventIdx = GlobalEventIdx

Either GlobalEventIdx or TargetedEventIdx. This indicates if the event is global or targeted.

type Mutability = Immutable

Indicates if this event is Mutable or Immutable.

fn init(_world: &mut World) -> EventKind

Gets the EventKind of this event and performs any necessary initialization work.

impl Hash for Spawn

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 Ord for Spawn

fn cmp(&self, other: &Spawn) -> 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 Spawn

fn eq(&self, other: &Spawn) -> 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 Spawn

fn partial_cmp(&self, other: &Spawn) -> 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.
