Struct Log2Map 

pub struct Log2Map { /* private fields */ }

Logarithmic mapping using log2. This is useful for frequency (Hz) values.

Implementations

impl Log2Map

pub fn new(min: f64, max: f64) -> Self

Create a new Log2Map for logarithmic mapping using log2. This is useful for frequency (Hz) values.

Arguments

• min - the minimum of the range, must be > 0.0
• max - the maximum of the range, must be > 0.0

Panics

• Panics when either min or max <= 0.0.

pub fn normalize(&self, value: f64) -> f64

Map an f64 value to the normalized range [0.0, 1.0].

pub fn normalize_array(&self, in_values: &[f64], out_normalized: &mut [f64])

Map an array of f64 values to the normalized range [0.0, 1.0].

Values will be processed up to the length of the shortest array.

pub fn denormalize(&self, normalized: f64) -> f64

Un-map a normalized value to the corresponding f64 value.

pub fn denormalize_array(&self, in_normalized: &[f64], out_values: &mut [f64])

Un-map an array of normalized values to the corresponding f64 value.

Values will be processed up to the length of the shortest array.

Trait Implementations

impl Debug for Log2Map

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

Formats the value using the given formatter.
