Struct LinearMapper 

pub struct LinearMapper { /* private fields */ }

Linear range mapping.

Maps values linearly between the range endpoints. Suitable for most parameters where perceptual response is linear.

Example

let mapper = LinearMapper::new(-60.0..=12.0);
assert_eq!(mapper.denormalize(0.0), -60.0);
assert_eq!(mapper.denormalize(1.0), 12.0);

Implementations

impl LinearMapper

pub fn new(range: RangeInclusive<f64>) -> Self

Create a new linear mapper with the given range.

Trait Implementations
