Function parse 

pub fn parse(content: &str, format: LockfileFormat) -> ParseResult

Parse a lockfile’s content given an already-known format.

Individual malformed entries become ParseWarnings; the returned ParseResult still contains the successfully extracted deps. A fatal error (e.g. invalid TOML/JSON) causes a panic-free empty result with a single warning. Use detect_and_parse if you want a Result on structural failures instead.
