pub struct EntityRow(/* private fields */);
Expand description
This represents the row or “index” of an Entity
within the Entities
table.
This is a lighter weight version of Entity
.
This is a unique identifier for an entity in the world.
This differs from Entity
in that Entity
is unique for all entities total (unless the Entity::generation
wraps),
but this is only unique for entities that are active.
This can be used over Entity
to improve performance in some cases,
but improper use can cause this to identify a different entity than intended.
Use with caution.
