Enum MappingStrategy 

pub enum MappingStrategy {
    Linear,
    Exponential {
        exponent: f32,
    },
    Logarithmic,
    Inverted,
}

Mapping strategy for translating normalized [0, 1] values to a parameter range.

Variants

Linear

Linear mapping: min + value * (max - min)

Exponential

Exponential mapping: min + value^exp * (max - min)

Fields

exponent: f32

Exponent for the exponential curve. Values > 1 emphasize the upper end; values < 1 emphasize the lower end.

Logarithmic

Logarithmic mapping: min + log(1 + value * (e - 1)) / log(e) * (max - min)

Inverted

Inverted linear mapping: max - value * (max - min)

Implementations

impl MappingStrategy

pub fn map<T: Transcendental>(&self, x: T, min: T, max: T) -> T

Map a normalized value x in [0, 1] to [min, max] using this strategy.

Trait Implementations

impl Clone for MappingStrategy

fn clone(&self) -> MappingStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MappingStrategy

impl Debug for MappingStrategy

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

Formats the value using the given formatter.

impl PartialEq for MappingStrategy

fn eq(&self, other: &MappingStrategy) -> 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.
