Function ambient_api::ecs::query

pub fn query<Components>(
    components: Components

where
    Components: ComponentsTuple + Copy + Clone + 'static,

Creates a new GeneralQueryBuilder that will find entities that have the specified components and can be built to create a GeneralQuery.

Building a query is somewhat expensive, but they are cheap to copy and evaluate, so it’s recommended that you build your queries once and reuse them elsewhere.
