Enum QualityPreset 

pub enum QualityPreset {
    Low,
    Medium,
    High,
    VeryHigh,
    Transparent,
}

Quality presets for lossy encoding

Variants

Low

Lowest quality, highest compression (~30:1) Good for speech, podcasts, low bandwidth

Medium

Medium quality, good compression (~10:1) Good for general music

High

High quality, moderate compression (~6:1) Good for quality-conscious listening

VeryHigh

Very high quality, light compression (~4:1) Near-transparent for most content

Transparent

Transparent quality, minimal loss (~3:1) Perceptually lossless for almost all content

Implementations

impl QualityPreset

pub fn as_f32(self) -> f32

Get the numeric quality value (0.0-1.0)

pub fn from_f32(quality: f32) -> Self

Create from numeric value

pub fn expected_ratio(self) -> f32

Estimate compression ratio for this quality level

pub fn equivalent_bitrate(self) -> u32

Estimate equivalent bitrate (kbps) for stereo 44.1kHz

pub fn from_bitrate(bitrate_kbps: u32, sample_rate: u32, channels: u8) -> Self

Create quality preset from target bitrate

Trait Implementations

impl Clone for QualityPreset

fn clone(&self) -> QualityPreset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QualityPreset

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

Formats the value using the given formatter.

impl From<QualityPreset> for u8

fn from(q: QualityPreset) -> u8

Converts to this type from the input type.

impl From<u8> for QualityPreset

fn from(v: u8) -> Self

Converts to this type from the input type.

impl PartialEq for QualityPreset

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