Struct RowOperation 

pub struct RowOperation {
    pub family: RowFamily,
    pub addend: u8,
}

A total affine/reversal operation on a strict tone row.

The addend is the affine constant in x -> x + addend for P/R and x -> -x + addend for I/RI. Values are reduced modulo twelve when the operation is applied, so even a struct literal containing an arbitrary u8 remains total.

Fields

family: RowFamily

Prime, inversion, retrograde, or retrograde-inversion family.

addend: u8

Affine addend, interpreted modulo twelve.

Implementations

impl RowOperation

pub const fn new(family: RowFamily, addend: u8) -> Self

Constructs a row operation with a canonical modulo-twelve addend.

pub const fn normalized(self) -> Self

Returns the canonical operation identity with its addend reduced modulo twelve.

pub const fn inverse(self) -> Self

Returns the exact inverse operation.
