email-address-parser

An RFC 5322 and RFC 6532 compliant email address parser.

You can parse a string as an email address like this.

use email_address_parser::EmailAddress;

let email = EmailAddress::parse("foo@bar.com", None).unwrap();
assert_eq!(email.get_local_part(), "foo");
assert_eq!(email.get_domain(), "bar.com");

For an input string that is an invalid email address, it returns None.

use email_address_parser::EmailAddress;

assert!(EmailAddress::parse("test@-iana.org", None).is_none());

To parse an email address with obsolete parts (as per RFC 5322), pass Some(ParsingOptions::new(true)) to enable lax parsing.

use email_address_parser::{EmailAddress, ParsingOptions};

let email = EmailAddress::parse(
    "\u{0d}\u{0a} \u{0d}\u{0a} test@iana.org",
    Some(ParsingOptions::new(true)),
);
assert!(email.is_some());

Unicode support

In compliance to RFC 6532, it supports parsing, validating, and instantiating email addresses with Unicode characters.

use email_address_parser::EmailAddress;

assert_eq!(
    format!("{}", EmailAddress::new("foö", "bücher.de", None).unwrap()),
    "foö@bücher.de"
);
assert_eq!(
    format!("{}", EmailAddress::parse("foö@bücher.de", None).unwrap()),
    "foö@bücher.de"
);
assert!(EmailAddress::is_valid("foö@bücher.de", None));
