Enum HierarchyEvent

pub enum HierarchyEvent {
    Modified(Entity),
    Removed(Entity),
}

Hierarchy events.

These are the events that are sent through the internal EventChannel in the Hierarchy resource.

Variants

Modified(Entity)

Entity was either inserted or modified in the Hierarchy

Removed(Entity)

Entity was removed from the Hierarchy. Note that this does not mean the Parent component was removed from the component storage, just that the Entity will no longer be considered to be a part of the Hierarchy.

Trait Implementations

impl Clone for HierarchyEvent

fn clone(&self) -> HierarchyEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HierarchyEvent

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

Formats the value using the given formatter.

impl Hash for HierarchyEvent

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 HierarchyEvent

fn eq(&self, other: &HierarchyEvent) -> 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.
