Enum QualityTarget 

pub enum QualityTarget {
    VisuallyLossless,
    High,
    Standard,
    Low,
    Vmaf(u8),
}

A single perceptual quality target, backend-agnostic.

Maps to VMAF / SSIMULACRA2 bands, NOT encoder CRF values:

Variant	Target VMAF	Target SSIMULACRA2	Use case
VisuallyLossless	~98	~90	Archive, master
High	~95	~80	Premium OTT / top ABR rung
Standard	~90	~70	Default web / streaming
Low	~85	~60	Mobile / bandwidth-constrained
Vmaf(u8)	explicit	n/a	A/B testing escape hatch

Variants

Trait Implementations

impl Clone for QualityTarget

fn clone(&self) -> QualityTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for QualityTarget

impl Debug for QualityTarget

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

Formats the value using the given formatter.

impl Default for QualityTarget

fn default() -> QualityTarget

Returns the “default value” for a type.

impl Eq for QualityTarget

impl PartialEq for QualityTarget

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