Enum ToleranceMetric 

pub enum ToleranceMetric {
    MaxAbsDiff(u32),
    MeanAbsDiff(f64),
    Psnr(f64),
    RmsError(f64),
}

Which metric to use for pass/fail decisions.

Variants

MaxAbsDiff(u32)

Maximum absolute difference must be ≤ threshold.

MeanAbsDiff(f64)

Mean absolute difference must be ≤ threshold.

Psnr(f64)

PSNR must be ≥ threshold (in dB). Higher is better.

RmsError(f64)

RMS error must be ≤ threshold.

Trait Implementations

impl Clone for ToleranceMetric

fn clone(&self) -> ToleranceMetric

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ToleranceMetric

impl Debug for ToleranceMetric

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

Formats the value using the given formatter.

impl Display for ToleranceMetric

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

Formats the value using the given formatter.

impl PartialEq for ToleranceMetric

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