use-domain

use-domain provides lightweight helpers for validating, normalizing, and inspecting domain names and hostnames.

Experimental: this crate is below 0.3.0 and the API may change.

Example Usage

use use_domain::{normalize_domain, root_domain_guess, split_domain_labels};

assert_eq!(normalize_domain("WWW.Example.com."), Some("www.example.com".to_string()));
assert_eq!(split_domain_labels("api.example.com"), vec!["api", "example", "com"]);
assert_eq!(root_domain_guess("api.example.com"), Some("example.com".to_string()));

Scope

• Domain and hostname validation.
• Domain normalization and label splitting.
• Small inspection helpers such as depth and subdomain checks.

Non-goals

• Complete public suffix list support.
• IDNA conversion.
• DNS lookup.
• Certificate validation.
