Enum MapCompositionWitness 

pub enum MapCompositionWitness {
    Direct {
        source_class: u16,
        via_value: i32,
        target_value: i32,
    },
    Undefined {
        source_class: u16,
        reason: &'static str,
    },
}

Witness for one source class while composing two pitch maps.

Variants

Direct

Fields

source_class: u16

Source class in the left map.

via_value: i32

Intermediate value produced by the left map.

target_value: i32

Target value produced by the right map.

Undefined

At least one direct image was absent.

Fields

source_class: u16

Source class in the left map.

reason: &'static str

Stable reason the composition is partial at this class.
