Module domain::bits::charstr [−][src]
Character strings.
The somewhat ill-named <character-string> is defined in RFC 1035 as
binary information of up to 255 bytes. As such, it doesn’t necessarily
contain (ASCII-) characters nor is it a string in the Rust-sense.
Character string are encoded as one octet giving the length followed by
the actual data in that many octets.
The type CharStr defined in this module wraps a bytes slice making
sure it always adheres to the length limit. It is an unsized type and
is typically used as a reference. Its owned companion is CharStrBuf.
When defining types that contain character strings, it is best to make
them generic over AsRef<CharStr> so that they can be used both with
&'a CharStr for borrowed data and CharStrBuf for owned data.
