Module hobo::query

Queries allow finding entities across the hierarchy

Examples

struct Foo {
	// some fields
}

// find the first (presumably only) entity with some component Foo
let (entity, _) = hobo::find_one::<(Entity, With<Foo>)>();
let element = SomeElement(entity);
element.set_text("This entity has Foo");

struct Frobnicator {
	num_fraculations: u32,
	// other fields
}

// find all entities with a Frobnicator component and mutate it
// perhaps as a result of some combined transformation
for frobnicator in hobo::find::<&mut Frobnicator>() {
	frobnicator.num_fraculations += 1;
}
