Struct Cents 

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

An interval in cents, a hundredth of a semitone: any finite value, sign allowed.

use sound_to_patch::units::Cents;

let detune = Cents::new(-7.0)?;
assert!(Cents::new(f64::INFINITY).is_err());

Implementations

impl Cents

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

Returns the frequency ratio 2^(c / 1200).

use sound_to_patch::units::Cents;

assert_eq!(Cents::new(1200.0)?.to_ratio()?, 2.0);

Errors

Returns a RangeError beyond ±1 200 000 cents, a conservative cap that keeps the ratio finite and nonzero.

pub fn from_ratio(ratio: f64) -> Result<Cents, RangeError>

Converts a frequency ratio: c = 1200 * log2(ratio). The result can lie beyond the cap of Cents::to_ratio: f64::MAX gives about 1 228 800 cents.

Errors

Returns a RangeError for a ratio of zero or less, or one that is not finite.

impl Cents

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