Crate email_validator_rfc5322

This crate provides email validation according to RFC 5322 Section 3.4.1 with support for:

• Standard email addresses (user@example.com)
• Quoted local parts ("john doe"@example.com)
• IP literal domains (user@[192.168.1.1], user@[IPv6:2001:db8::1])
• All RFC 5322 special characters in local parts

Examples

use email_validator_rfc5322::{validate_email, is_valid_email};

// Simple validation
assert!(is_valid_email("user@example.com"));
assert!(!is_valid_email("invalid"));

// With error details
match validate_email("user@example.com") {
    Ok(()) => println!("Valid email"),
    Err(e) => println!("Invalid: {:?}", e),
}
