Struct FileCoverage 

pub struct FileCoverage {
    pub path: String,
    pub lines: BTreeMap<u32, u64>,
}

Per-line hit counts for a single source file.

Only executable lines are present in lines; a line absent from the map is not instrumented (blank, comment, etc.) and must not be counted towards coverage totals.

Fields

path: String

Repo-relative path of the source file.

lines: BTreeMap<u32, u64>

Map of 1-based line number to hit count.

Implementations

impl FileCoverage

pub fn new(path: impl Into<String>) -> Self

Creates an empty file coverage for path.

pub fn record(&mut self, line: u32, hits: u64)

Records hits for line. Repeated records for the same line take the maximum, so a line covered by any region counts as covered.

pub fn total_lines(&self) -> u64

Number of executable lines.

pub fn covered_lines(&self) -> u64

Number of executable lines hit at least once.

pub fn percent(&self) -> Option<f64>

Line coverage percentage, or None when the file has no executable lines.

Trait Implementations

impl Clone for FileCoverage

fn clone(&self) -> FileCoverage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileCoverage

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

Formats the value using the given formatter.

impl Eq for FileCoverage

impl PartialEq for FileCoverage

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