Expand description

This crates implements a parser for text that meets the grammar for “quoted-string” as described in SIP: Session Initiation Protocol. RFC3261

 quoted-string  =  SWS DQUOTE *(qdtext / quoted-pair ) DQUOTE
 qdtext         =  LWS / %x21 / %x23-5B / %x5D-7E / UTF8-NONASCII
 quoted-pair    =  "\" (%x00-09 / %x0B-0C / %x0E-7F)
 LWS            =  [*WSP CRLF] 1*WSP ; linear whitespace
 SWS            =  [LWS] ; sep whitespace
 UTF8-NONASCII  =  %xC0-DF 1UTF8-CONT
                /  %xE0-EF 2UTF8-CONT
                /  %xF0-F7 3UTF8-CONT
                /  %xF8-Fb 4UTF8-CONT
                /  %xFC-FD 5UTF8-CONT
 UTF8-CONT      =  %x80-BF
 DQUOTE         =  %x22      ; " (Double Quote)
 CRLF           =  CR LF     ; Internet standard newline
 CR             =  %x0D      ; carriage return
 LF             =  %x0A      ; linefeed
 WSP            =  SP / HTAB ; whitespace
 SP             =  %x20
 HTAB           =  %x09      ; horizontal tab
