Enum LossBucket 

pub enum LossBucket {
    Lossless,
    NearLossless,
    LowLoss,
    Moderate,
    High,
}

Perceptual loss buckets, calibrated against CIEDE2000 measurements.

Promoted from test-only type to public API for use with QualityThreshold.

Variants

Lossless

ΔE < 0.5 — below just-noticeable difference. Model loss ≤ 10.

NearLossless

ΔE 0.5–2.0 — visible only in side-by-side comparison. Model loss 11–50.

LowLoss

ΔE 2.0–5.0 — minor visible differences. Model loss 51–150.

Moderate

ΔE 5.0–15.0 — clearly visible quality difference. Model loss 151–400.

High

ΔE > 15.0 — severe quality degradation. Model loss > 400.

Implementations

impl LossBucket

pub fn from_model_loss(loss: u16) -> Self

Classify a model loss value into a bucket.

pub fn max_loss(self) -> u16

Maximum model loss value for this bucket.

Trait Implementations

impl Clone for LossBucket

fn clone(&self) -> LossBucket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LossBucket

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

Formats the value using the given formatter.

impl Hash for LossBucket

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LossBucket

fn cmp(&self, other: &LossBucket) -> 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 LossBucket

fn eq(&self, other: &LossBucket) -> 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 LossBucket

fn partial_cmp(&self, other: &LossBucket) -> 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.
