Trait ResourceQueryMut

pub trait ResourceQueryMut {
    type MutItem<'r>;
    type State<'s>: QueryState<'s>;

    // Required method
    fn query_mut<'r, 's>(
        resources: &'r mut Resources,
        state: Self::State<'s>,
    ) -> Option<Self::MutItem<'r>>;
}

Required Associated Types

type MutItem<'r>

type State<'s>: QueryState<'s>

Required Methods

fn query_mut<'r, 's>( resources: &'r mut Resources, state: Self::State<'s>, ) -> Option<Self::MutItem<'r>>

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.
