Trait ImmediateQuery

Required Methods

fn query_single<D>( &mut self, ) -> Result<<D as WorldQuery>::Item<'_>, QuerySingleError>

where D: ReadOnlyQueryData,

fn query_single_filtered<D, F>( &mut self, ) -> Result<<D as WorldQuery>::Item<'_>, QuerySingleError>

where D: ReadOnlyQueryData, F: QueryFilter,

fn query_collect<D, C>(&mut self) -> C

where D: ReadOnlyQueryData, for<'a> C: FromIterator<<D as WorldQuery>::Item<'a>>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
