Struct NoiseFloor 

pub struct NoiseFloor {
    pub suite: String,
    pub items_compared: usize,
    pub unpaired_items: usize,
    pub pass_rate: f64,
    pub judge_score: f64,
    pub suite_pass_rate: f64,
    pub moved: Vec<ItemNoise>,
}

How much the unchanged system moved when it was measured twice.

Fields

suite: String

The suite the control run measured.

items_compared: usize

How many items appeared in both passes.

unpaired_items: usize

How many appeared in only one, and therefore said nothing.

pass_rate: f64

The largest absolute movement in any one item’s deterministic pass rate. This is the number a pass-rate difference is judged against.

judge_score: f64

The largest absolute movement in any one item’s mean judge score.

suite_pass_rate: f64

The movement of the suite-wide pass rate, for a reader who wants the headline rather than the worst item.

moved: Vec<ItemNoise>

Every item that moved at all, worst first is not assumed — they are in suite order, so the list reads like the corpus.

Implementations

impl NoiseFloor

pub fn deterministic(suite: impl Into<String>) -> Self

A floor of exactly zero, for a system asserted to be deterministic.

Use it when a corpus is scripted end to end and any movement at all is news. It is not a default: assuming a floor of zero without measuring one is the assumption this module exists to replace.

pub fn is_flat(&self) -> bool

Returns true when nothing moved between the two passes.

pub fn covers_pass_rate(&self, delta: f64) -> bool

Returns true when a pass-rate difference is no larger than the movement the unchanged system produced.

pub fn covers_judge_score(&self, delta: f64) -> bool

Returns true when a judge-score difference is no larger than the movement the unchanged system produced.

pub fn summary(&self) -> String

A readable rendering.

Trait Implementations

impl Clone for NoiseFloor

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoiseFloor

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

Formats the value using the given formatter.

impl Default for NoiseFloor

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NoiseFloor

where NoiseFloor: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
