Struct Semitones 

pub struct Semitones(/* private fields */);

An interval in semitones: any finite value, sign allowed.

use sound_to_patch::units::Semitones;

let octave_down = Semitones::new(-12.0)?;
assert!(Semitones::new(f64::NAN).is_err());

Implementations

impl Semitones

pub fn to_ratio(self) -> Result<f64, RangeError>

Returns the frequency ratio 2^(s / 12).

Errors

Returns a RangeError beyond ±12 000 semitones, a conservative cap that keeps the ratio finite and nonzero.

impl Semitones

pub fn new(value: f64) -> Result<Semitones, RangeError>

Checks the value against the range of the type.

Errors

Returns a RangeError for NaN, an infinity or a value outside the range.

pub fn get(self) -> f64

Returns the inner value.

Trait Implementations

impl Clone for Semitones

fn clone(&self) -> Semitones

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Semitones

impl Debug for Semitones

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

impl Display for Semitones

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

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Semitones

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,
