pub fn parse_coverage_py(content: &str) -> HashMap<PathBuf, FileCoverage>Expand description
Parse a coverage.py native JSON report (coverage json) into a per-file coverage map.
coverage.py’s own JSON schema differs from Istanbul’s json-summary: it nests per-file data
under a top-level files object, with line/branch counts in each file’s summary block.
coverage.py does not track function-level coverage, so functions_* are always zero.
