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).

Use [as_bytes()] to get a byte slice of the underlying UID.

Examples

use bloop_server_framework::nfc_uid::NfcUid;

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

Variants

Single([u8; 4])

Double([u8; 7])

Triple([u8; 10])

Implementations

impl NfcUid

pub fn as_bytes(&self) -> &[u8]

pub fn to_vec(&self) -> Vec<u8>

Trait Implementations

impl Clone for NfcUid

fn clone(&self) -> NfcUid

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NfcUid

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NfcUid

fn default() -> Self

Returns the “default value” for a type.

impl FromHex for NfcUid

type Error = FromHexError

fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>

Creates an instance of type Self from the given hex string, or fails with a custom error type.

impl Hash for NfcUid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NfcUid

fn eq(&self, other: &NfcUid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&[u8]> for NfcUid

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<u8>> for NfcUid

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Vec<u8>) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for NfcUid

impl Eq for NfcUid

impl StructuralPartialEq for NfcUid
