Struct FileCoverage 

pub struct FileCoverage {
    pub lines_covered: RoaringBitmap,
    pub lines_instrumented: RoaringBitmap,
    pub branches: BTreeMap<(u32, u32), u64>,
    pub functions: BTreeMap<String, u64>,
}

Coverage data for a single file.

Fields

lines_covered: RoaringBitmap

Lines that were executed at least once.

lines_instrumented: RoaringBitmap

Lines that are instrumented (could be executed).

branches: BTreeMap<(u32, u32), u64>

Branch coverage: (line, block) → taken count. Optional.

functions: BTreeMap<String, u64>

Function coverage: name → hit count. Optional.

Implementations

impl FileCoverage

pub fn new() -> Self

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

Line coverage percentage (0.0–100.0). Returns None if no instrumented lines.

pub fn merge(&mut self, other: &FileCoverage)

Merge another FileCoverage into this one (OR for bitmaps, sum for counts).

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 Default for FileCoverage

fn default() -> Self

Returns the “default value” for a type.
