Struct GeneratedCoverageReport 

pub struct GeneratedCoverageReport {
    pub language: Symbol,
    pub sampled: usize,
    pub round_tripped: usize,
    pub mismatched: usize,
    pub diagnostics: usize,
    pub max_depth: usize,

A reproducible measurement of generated expression round-trip coverage.

Fields

language: Symbol

Language row measured by this report.

sampled: usize

Number of generated cases sampled.

round_tripped: usize

Number of sampled cases that round-tripped.

mismatched: usize

Number of sampled cases that decoded to a different expression.

diagnostics: usize

Number of sampled cases that produced diagnostics or declared gaps.

max_depth: usize

Maximum expression depth used by the space.

seed: Vec<Expr>

Seed corpus used as the landmark gate for this measurement.

landmark_reproduced: bool

Whether every seed landmark round-tripped before coverage reporting.

unmet_landmarks: Vec<Expr>

Seed expressions that did not round-trip before measurement.

Implementations

impl GeneratedCoverageReport

pub fn landmark_reproduced(&self) -> bool

Returns true when every seed landmark round-tripped.

pub fn coverage(&self) -> Option<f32>

Coverage ratio, round_tripped / sampled.

Returns None when seed landmark reproduction did not pass or the run sampled no generated cases.

pub fn coverage_percent(&self) -> Option<f32>

Coverage percentage, derived from GeneratedCoverageReport::coverage.

Trait Implementations

impl Clone for GeneratedCoverageReport

fn clone(&self) -> GeneratedCoverageReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeneratedCoverageReport

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

Formats the value using the given formatter.

impl Eq for GeneratedCoverageReport

impl PartialEq for GeneratedCoverageReport

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