Struct VolumeDb 

pub struct VolumeDb(pub i16);

Volume in 8.8 fixed-point dB format (USB Audio spec)

The USB Audio Class represents volume as a signed 16-bit value in 1/256 dB steps. The integer part is the upper 8 bits (signed), the fractional part is the lower 8 bits.

Examples:

• 0x0000 = 0.0 dB (unity gain)
• 0x0100 = +1.0 dB
• 0xFF00 = -1.0 dB (two’s complement)
• 0x8000 = -128.0 dB (silence)
• 0x7FFF = +127.99609375 dB (max)

Trait Implementations

impl Clone for VolumeDb

fn clone(&self) -> VolumeDb

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VolumeDb

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

Formats the value using the given formatter.

impl Ord for VolumeDb

fn cmp(&self, other: &VolumeDb) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VolumeDb

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