Enum bones_lib::ecs::prelude::QuerySingleError

pub enum QuerySingleError {
    NoEntities,
    MultipleEntities,
}
Expand description

An error that may occur when querying for a single entity. For example, via Entities::get_single_with, or more directly with ComponentStore::get_single_with_bitset or ComponentStore::get_single_mut_with_bitset.

Variants§

§

NoEntities

No entity matches the query.

§

MultipleEntities

More than one entity matches the query.
