Struct CenterSliderInput 

#[repr(transparent)]
pub struct CenterSliderInput {
    pub position: f32,
}

A continuous fader or knob with a symmetric center position.

Fields

position: f32

Position in the interval [-1, 1]

Implementations

impl CenterSliderInput

pub const MIN_POSITION: f32 = -1f32

pub const MAX_POSITION: f32 = 1f32

pub const POSITION_RANGE: RangeInclusive<f32>

pub const CENTER_POSITION: f32 = 0f32

pub const fn clamp_position(position: f32) -> f32

pub fn from_u7(input: u8) -> Self

pub fn from_u14(input: u16) -> Self

pub fn inverse(self) -> Self

pub fn map_position_linear<T>( self, min_value: T, center_value: T, max_value: T, ) -> T

where T: From<f32> + Sub<Output = T> + Mul<Output = T> + Add<Output = T> + Copy + PartialOrd,

pub fn map_position_to_gain_ratio(self, min_db: f32, max_db: f32) -> f32

Interpret the position as a ratio for tuning the volume of a signal.

The position is interpreted as a volume level between the min_db (< 0 dB) and max_db (> 0 dB), e.g. -26 dB and +6 dB (Pioneer DJM).

Multiply the signal with the returned value to tune the volume.

Trait Implementations

impl Clone for CenterSliderInput

fn clone(&self) -> CenterSliderInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CenterSliderInput

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

Formats the value using the given formatter.

impl From<CenterSliderInput> for ControlValue

fn from(from: CenterSliderInput) -> Self

Converts to this type from the input type.

impl From<ControlValue> for CenterSliderInput

fn from(from: ControlValue) -> Self

Converts to this type from the input type.

impl PartialEq for CenterSliderInput

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