Struct DbMeterNormalizer 

pub struct DbMeterNormalizer { /* private fields */ }

A struct that converts a value in decibels to a normalized range used in meters.

Implementations

impl DbMeterNormalizer

pub fn new(min_db: f32, max_db: f32, center_db: f32) -> Self

• min_db - The minimum decibel value shown in the meter.
• max_db - The maximum decibel value shown in the meter.
• center_db - The decibel value that will appear halfway (0.5) in the normalized range. For example, if you had min_db as -100.0 and max_db as 0.0, then a good center_db value would be -22.

pub fn normalize(&self, db: f32) -> f32

Trait Implementations

impl Clone for DbMeterNormalizer

fn clone(&self) -> DbMeterNormalizer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DbMeterNormalizer

impl Debug for DbMeterNormalizer

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

Formats the value using the given formatter.

impl Default for DbMeterNormalizer

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DbMeterNormalizer

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