Struct LayeredKey

Source
pub struct LayeredKey<R: Copy + Debug + PartialEq> {
    pub base: R,
    pub layered: [Option<R>; 8],
}
Expand description

A key whose behavior depends on which layer is active.

Fields§

§base: R

The base key, used when no layers are active.

§layered: [Option<R>; 8]

The layered keys, used when the corresponding layer is active.
