Enum NfcUid 

pub enum NfcUid {
    Single([u8; 4]),
    Double([u8; 7]),
    Triple([u8; 10]),
}

Represents an NFC UID of standard lengths.

NFC UIDs come in three typical sizes:

• Single: 4 bytes
• Double: 7 bytes
• Triple: 10 bytes

This enum encapsulates these variants and ensures correct sizing during construction via TryFrom<&[u8]> or hex parsing (FromHex, behind the hex feature). On the wire a UID is its length as u8 followed by the UID bytes.

Examples

use bloop_protocol::nfc_uid::NfcUid;

let uid = NfcUid::try_from(&[0x01, 0x02, 0x03, 0x04][..])?;
assert_eq!(uid.as_bytes(), &[0x01, 0x02, 0x03, 0x04]);

Variants

Single([u8; 4])

4-byte UID.

Double([u8; 7])

7-byte UID.

Triple([u8; 10])

10-byte UID.
