Struct ReplayGain 

pub struct ReplayGain {
    pub track_gain_db: Option<f32>,
    pub album_gain_db: Option<f32>,
    pub track_peak: Option<f32>,
    pub album_peak: Option<f32>,
    pub raw_track_gain: i64,
    pub raw_album_gain: i64,
    pub raw_track_peak: i64,
    pub raw_album_peak: i64,
}

ReplayGain values parsed from the file’s tags.

The *_db / *_peak fields are user-friendly conversions; the raw_* fields keep Rockbox’s native fixed-point encoding — linear scale factors in Q7.24, exactly what rockbox-dsp’s set_replaygain_gains_raw() expects.

Fields

track_gain_db: Option<f32>

Track gain in dB (e.g. -6.5), if the tag is present.

album_gain_db: Option<f32>

Album gain in dB, if the tag is present.

track_peak: Option<f32>

Track peak amplitude, 1.0 = full scale.

album_peak: Option<f32>

Album peak amplitude, 1.0 = full scale.

raw_track_gain: i64

Track gain as a linear Q7.24 scale factor (0 = tag absent).

raw_album_gain: i64

Album gain as a linear Q7.24 scale factor (0 = tag absent).

raw_track_peak: i64

Track peak in Q7.24 (0 = tag absent).

raw_album_peak: i64

Album peak in Q7.24 (0 = tag absent).

Implementations

impl ReplayGain

pub fn is_empty(&self) -> bool

True if no ReplayGain information was found at all.

Trait Implementations

impl Clone for ReplayGain

fn clone(&self) -> ReplayGain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ReplayGain

impl Debug for ReplayGain

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

Formats the value using the given formatter.

impl Default for ReplayGain

fn default() -> ReplayGain

Returns the “default value” for a type.

impl PartialEq for ReplayGain

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