ascii_domain

ascii_domain is a library for efficiently parsing domains based on a supplied ASCII character set one wants to enforce each Label to conform to. The primary type in the library is Domain which can be thought of as a domain in representation format. Technically since any ASCII u8 except b'.' is allowed in a Label, it is more general than an actual representation format that doesn't include some form of escape characters. For a full-fledged DNS library look elsewhere (e.g., domain).

The purpose of this library is to allow efficient customization of domain name parsing while still retaining the hierarchical structure of a domain. Depending on one’s use case, allowed formats and characters can differ. If one wants to conform to the Domain Name System (DNS), all octets are allowed; but conforming to RFC 1123 or RFC 5891 requires stricter formats and a reduced character set.
