This crate allows basic manipulation of FQDN with an inner representation compatible with the RFC 1035.
So, all comparisons between character strings (e.g., labels, domain names, etc.) are done in a case-insensitive manner. Of course, FQDN hashing should follow this behaviour.
Notice that this RFC introduces some size limits which are not defaulty
set by this crate.
The feature strict-rfc-1035 activates all of them
but each of them could be activated independently of the others:
- labels are limited to 63 octets (domain-label-length-limited-to-63)
- names are limited to 255 octets (domain-name-length-limited-to-255)
- labels should start with a letter (domain-label-should-start-with-letter)
- labels should only contain letters, digits and hyphen (domain-name-without-special-chars)
