Enum ScalaDegree 

pub enum ScalaDegree {
    Ratio(Fraction),
    Cents(FloatType),
}

A single degree of a ScalaScale.

Scala files express each degree either as an exact ratio (3/2) or as a cents value (701.955). The distinction is preserved rather than collapsed, because a ratio carries exactness that cents cannot express.

Variants

Ratio(Fraction)

An exact integer ratio, such as 3/2.

Cents(FloatType)

A cents value above the scale root, such as 701.955.

Implementations

impl ScalaDegree

pub fn ratio(self) -> FloatType

Returns this degree as a frequency ratio above the scale root.

pub fn cents(self) -> FloatType

Returns this degree in cents above the scale root.

pub fn as_fraction(self) -> Option<Fraction>

Returns the exact ratio, when this degree was written as one.

Trait Implementations

impl Clone for ScalaDegree

fn clone(&self) -> ScalaDegree

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ScalaDegree

impl Debug for ScalaDegree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ScalaDegree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ScalaDegree

fn eq(&self, other: &ScalaDegree) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
