Struct Db

pub struct Db(/* private fields */);

This represents a volume measured in decibel.

Implementations

impl Db

pub const MIN: Db = Db::MINUS_INF

The minimum possible value (= MINUS_INF).

There’s no maximum value because REAPER allows to exceed the “soft maximum” of 12 dB!

pub const NAN: ReaperVolumeValue

The not-a-number volume (f64::NAN = 1.#R dB).

See ReaperVolumeValue::NAN.

pub const MINUS_INF: Db

The negative infinity volume (-1000.0 = -inf dB).

pub const MINUS_150_DB: Db

The “soft minimum” volume (-150.0 dB).

pub const ZERO_DB: Db

The “unaltered” volume (0.0 dB).

pub const TWELVE_DB: Db

The “soft maximum” volume (12.0 dB).

pub fn new(value: f64) -> Db

Creates a decibel value.

Panics

This function panics if the given value is not within the decibel range supported by REAPER (-1000.0..).

pub const fn get(&self) -> f64

Returns the wrapped value.

Trait Implementations

impl Clone for Db

fn clone(&self) -> Db

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Db

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

Formats the value using the given formatter.

impl Default for Db

fn default() -> Db

Returns the “default value” for a type.

impl Display for Db

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

Formats the value using the given formatter.

impl PartialEq for Db

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

impl PartialOrd for Db

fn partial_cmp(&self, other: &Db) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
