lut lookup tables for parsing media types
Structs
CText characters
The characters mainly needing escaping (just
'"' and '\\')HttToken character allowed in a token given the grammar from RFC7230 (http)
MediaTypeChars is a lookup table for a number of character classes relevant when parsing media types
ObsNoWsCtl characters of the
obs- part of the mime grammar which are not ws and not ctl
by combining this with other classes the obs- part of the grammar can be supported
e.g. QText + ObsNoWsCtl == ObsQText i.e. QText in the obs- grammarQText incl. obs-parts of the mime grammar
QText incl. obs-parts (mime) or ws
QText characters, i.e. characters which can appear in a quoted string
without being escaped through quoted pairs
QText or Ws chars
Restricted Token, character allowed in a token wrt. to registering media types at IANA,
any registered media type has to be compatible with this any other should be, through
there is no guarantee for it.
Token (Mime) characters allowed in a token given the grammar from RFC2045 (mime)
VChar printable us-ascii chars (i.e.
'!' <= ch && ch <= '~')VChar or Ws (i.e.
(' ' <= ch && ch <= '~') || ch == '\t')Ws (just
'\t' and '\r')
