MacAddress

Struct MacAddress 

Source
pub struct MacAddress(/* private fields */);
Available on crate feature net only.
Expand description

A MAC address.

This type provides type-safe MAC addresses with IEEE 802 validation. It uses the newtype pattern with #[repr(transparent)] for zero-cost abstraction.

§Invariants

  • Exactly 6 bytes (48 bits)
  • Each octet is 0-255

§Examples

use bare_types::net::MacAddress;

// Create a MAC address
let mac = MacAddress::new([0x00, 0x11, 0x22, 0x33, 0x44, 0x55])?;

// Access the string representation
assert_eq!(mac.as_str(), "00:11:22:33:44:55");

// Check if it's unicast
assert!(mac.is_unicast());

// Get the octets
assert_eq!(mac.octets(), [0x00, 0x11, 0x22, 0x33, 0x44, 0x55]);

// Parse from string
let mac: MacAddress = "00:11:22:33:44:55".parse()?;
