Function parse_request 

pub fn parse_request<'b, 'h>(
    buf: &'b [u8],
    hs: &'h mut [Header<'b>],
    lim: &Limits,
) -> Result<Status<Request<'b, 'h>>, Error>

Parses a whole request head from the start of buf into hs.

Returns Partial until the head is complete; limits are enforced on partial input too. The parse never allocates. For input that arrives in pieces, RequestParser avoids parsing the same bytes again until a head can be complete.
