Enum specs::storage::ComponentEvent

pub enum ComponentEvent {
    Inserted(Index),
    Modified(Index),
    Removed(Index),
}

Component storage events received from a FlaggedStorage or any storage that implements Tracked.

Variants

Inserted(Index)

An insertion event, note that a modification event will be triggered if the entity already had a component and had a new one inserted.

Modified(Index)

A modification event, this will be sent any time a component is accessed mutably so be careful with joins over &mut storages as it could potentially flag all of them.

Removed(Index)

A removal event.

Trait Implementations

impl Clone for ComponentEvent

fn clone(&self) -> ComponentEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentEvent

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

Formats the value using the given formatter.

impl PartialEq<ComponentEvent> for ComponentEvent

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