Function parse 

pub fn parse(
    raw_path: &str,
    raw_query: Option<&str>,
    prefix: RepoPrefix,
) -> Result<ParsedUrl, BadUrl>

Parse a request’s escaped path and query per §2. The caller passes the path exactly as received: framework decoding must not reinterpret delimiters. A # anywhere is invalid.

Errors

BadUrl for any §2 violation.
