Function parse_origin_form 

pub fn parse_origin_form(
    target: &[u8],
    merge_slashes: bool,
) -> Result<Parsed<'_>, ParseError>

Parse a single origin-form request target exactly as nginx does.

An origin-form target is the absolute path and optional query string that a client puts on the request line, for example /docs/../hello%20world?x=1 (see RFC 9112 §3.2.1).

The return value consists of path and args, which correspond to nginx’s $uri and $args respectively.

• Ok(Parsed) — the normalized path and query string. For a “simple” path that needs no normalization, the path borrows the input unchanged (Cow::Borrowed) with no allocation; normalization returns an owned buffer (Cow::Owned). The query string always borrows the input.
• Err(ParseError) — the request target could not be parsed.

merge_slashes corresponds to nginx’s merge_slashes directive: true is on (the nginx default), and false is off.
