Function reg_name 

pub fn reg_name<S: Spec>(s: &str) -> Result<(), Error>

Validates reg-name.

Examples

use iri_string::{spec::UriSpec, validate::reg_name};
assert!(reg_name::<UriSpec>("example.com").is_ok());
assert!(reg_name::<UriSpec>("subdomain.example.com").is_ok());
assert!(reg_name::<UriSpec>("no-period").is_ok());
// Though strongly discouraged, this percent-encoded reg-name with
// non-UTF-8 bytes is considered syntactically valid.
assert!(reg_name::<UriSpec>("non-%99-utf-8").is_ok());
// Empty host is valid. Remember `file:///` has empty authority (and empty host).
assert!(reg_name::<UriSpec>("").is_ok());

// Even if this looks similar to `IPv4address`, it's not,
// and this matches `reg-name` rule.
assert!(reg_name::<UriSpec>("127.0.0.256").is_ok());

// IP addresses are not a `reg-name`.
assert!(reg_name::<UriSpec>("127.0.0.1").is_err());
assert!(reg_name::<UriSpec>("[::1]").is_err());
assert!(reg_name::<UriSpec>("[::127.0.0.1]").is_err());
// Syntax for future versions of IP addresses.
assert!(reg_name::<UriSpec>("[v89ab.1+2,3(4)5&6]").is_err());

// `port` is not a part of the host.
assert!(reg_name::<UriSpec>("host:8080").is_err());
// `userinfo` is not a part of the host.
assert!(reg_name::<UriSpec>("user:password@host").is_err());
