//! Parse degradation reported for a source file.

/// How much of the file the parser actually understood.
///
/// oxc reports recoverable errors for valid-but-newer syntax as well as for
/// genuinely broken sources, so this is reporting data only: extraction keeps
/// every symbol it found, and no finding is ever withheld because of it. What
/// it buys is honesty about the case where a file failed to parse and its
/// imports therefore never credited anything, which otherwise surfaces as a
/// confident `unused-file` finding on the file that was in fact imported.
