Struct libpulse_binding::volume::VolumeDB

pub struct VolumeDB(pub f64);

Software volume expressed in decibels (dBs).

Implementations

impl VolumeDB

pub const MINUS_INFINITY: Self

Minus Infinity.

This floor value is used / can be used, when using converting between integer software volume and decibel (dB, floating point) software volume.

Trait Implementations

impl Clone for VolumeDB

fn clone(&self) -> VolumeDB

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for VolumeDB

impl Debug for VolumeDB

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

Formats the value using the given formatter.

impl Default for VolumeDB

fn default() -> Self

Returns the "default value" for a type.

impl From<Volume> for VolumeDB

Converts a volume to a decibel value (amplitude, not power).

This is only valid for software volumes!

fn from(v: Volume) -> Self

Performs the conversion.

impl From<VolumeDB> for Volume

Converts a decibel value to a volume (amplitude, not power).

This is only valid for software volumes!

fn from(v: VolumeDB) -> Self

Performs the conversion.

impl From<VolumeDB> for VolumeLinear

Converts a decibel value (amplitude, not power) to a linear factor.

This is only valid for software volumes!

fn from(v: VolumeDB) -> Self

Performs the conversion.

impl From<VolumeLinear> for VolumeDB

Converts a linear factor to a decibel value (amplitude, not power).

0.0 and less is muted while 1.0 is Volume::NORMAL.

This is only valid for software volumes!

fn from(v: VolumeLinear) -> Self

Performs the conversion.

impl PartialEq<VolumeDB> for VolumeDB

fn eq(&self, other: &VolumeDB) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &VolumeDB) -> bool

This method tests for !=.

impl PartialOrd<VolumeDB> for VolumeDB

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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