      7 `ascii_domain` is a library for efficiently parsing domains based on a supplied ASCII character set one wants to
      8 enforce each `Label` to conform to. The primary type in the library is `Domain` which can be thought of as a domain
      9 in _representation_ format. Technically since any ASCII `u8` except `b'.'` is allowed in a `Label`, it is more
     10 general than an actual representation format that doesn't include some form of escape characters. For a
     11 full-fledged DNS library look elsewhere (e.g., [`domain`](https://docs.rs/domain/latest/domain/)).
     12 
     13 The purpose of this library is to allow efficient customization of domain name parsing while still retaining
     14 the hierarchical structure of a domain. Depending on one’s use case, allowed formats and characters can
     15 differ. If one wants to conform to the [Domain Name System (DNS)](https://www.rfc-editor.org/rfc/rfc2181),
     16 all octets are allowed; but conforming to [RFC 1123](https://www.rfc-editor.org/rfc/rfc1123) or
     17 [RFC 5891](https://datatracker.ietf.org/doc/html/rfc5891) requires stricter formats and a reduced character
     18 set.

     20 ## Minimum Supported Rust Version (MSRV)
     21 
     22 This will frequently be updated to be the same as stable. Specifically, any time stable is updated and that
     23 update has "useful" features or compilation no longer succeeds (e.g., due to new compiler lints), then MSRV
     24 will be updated.
     25 
     26 MSRV changes will correspond to a SemVer patch version bump pre-`1.0.0`; otherwise a minor version bump.
     27 
     28 ## SemVer Policy
     29 
     30 * All on-by-default features of this library are covered by SemVer
     31 * MSRV is considered exempt from SemVer as noted above

     43

     46 
     47 Before any PR is sent, `cargo clippy` and `cargo t` should be run for both `--no-default-features` and
     48 `--all-features`. Additionally `RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc --all-features` should be run to
     49 ensure documentation can be built.
     50 
     51 ### Status
     52 
     53 The crate is only tested on the `x86_64-unknown-linux-gnu` and `x86_64-unknown-openbsd` targets, but
     54 it should work on any platform.
