Struct bevy_ecs::query::EntityFetch [−][src]
pub struct EntityFetch { /* fields omitted */ }
Trait Implementations
type State = EntityState
Returns true if (and only if) every table of every archetype matched by this Fetch contains
all of the matched components. This is used to select a more efficient “table iterator”
for “dense” queries. If this returns true, Fetch::set_table
and Fetch::table_fetch
will be called for iterators. If this returns false, Fetch::set_archetype
and
Fetch::archetype_fetch
will be called for iterators. Read more
