pub fn parse_location_line(line: &str) -> Option<CompilationLocation>Expand description
CM.3b: parse a source location out of ONE *compilation* buffer
line — the <CR>-jump seam. Runs the built-in rustc---> and
gnu-style location regexes (the same compiled patterns the
streaming parsers use, via [crate::parsers::match_location_line])
against the line and returns the first match, converting 1-based
line/col to 0-based. None when the line carries no navigable
location (progress, summary, backtraces, prose).
Deliberately independent of the streaming ParserRegistry’s
pending multi-line state: stdout/stderr interleave in the buffer,
so a buffer-line→entry map isn’t reliable. Parsing the cursor line
directly is interleaving-proof and covers both the gnu lines and
the cargo --> location line. CM.3c’s severity gutter decoration
reuses this exact function.
