Trait ComponentQueryMut

pub trait ComponentQueryMut {
    type MutItem<'t>;
    type State<'s>: QueryState<'s>;

    // Required method
    fn query_mut<'t, 's>(
        tiles: &'t mut Tiles,
        tile: Tile,
        state: Self::State<'s>,
    ) -> Option<Self::MutItem<'t>>;
}

Required Associated Types

type MutItem<'t>

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

Required Methods

fn query_mut<'t, 's>( tiles: &'t mut Tiles, tile: Tile, state: Self::State<'s>, ) -> Option<Self::MutItem<'t>>

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.
