pub struct FileCoverage {
pub lines: BTreeMap<u32, u64>,
}Expand description
Per-file coverage, indexed by line number.
Only lines that appear in a DA record are tracked — these are the
“executable” lines per LLVM’s coverage mapping. Blank lines, comments,
and purely declarative lines (use statements, struct definitions) do
not appear here, and we treat them as “not applicable” rather than
“uncovered”.
Fields§
§lines: BTreeMap<u32, u64>Line number (1-indexed) → hit count.
Implementations§
Source§impl FileCoverage
impl FileCoverage
Sourcepub fn coverage_in_span(&self, start: usize, end: usize) -> f64
pub fn coverage_in_span(&self, start: usize, end: usize) -> f64
Percentage of executable lines in [start..=end] that were hit at
least once.
Returns 100.0 if no executable lines fall inside the span. A function
composed entirely of declarative code (fn sig() -> Type;, unreachable
macro expansions, etc.) genuinely has nothing to cover and should not
be penalized.
