Struct Eui 

pub struct Eui(/* private fields */);

A gateway’s unique identifier, the eight bytes it puts in every datagram it sends.

It is written from the host’s MAC address, usually with FF FE in the middle, which is why a Raspberry Pi gateway’s identifier starts with the three bytes of its network interface.

Examples

use pamoja_gateway::udp::Eui;

let gateway = Eui::from_hex("b827ebfffe010203").expect("sixteen hex digits");
assert_eq!(gateway.to_hex(), "b827ebfffe010203");
assert_eq!(gateway.bytes()[0], 0xB8);

Implementations

impl Eui

pub const fn new(bytes: [u8; 8]) -> Eui

Takes the eight bytes as they go on the wire.

Arguments

• bytes - the identifier, most significant byte first.

Returns

The identifier.

pub const fn bytes(&self) -> [u8; 8]

Returns the bytes.

Returns

The identifier as it goes on the wire.

pub fn from_hex(text: &str) -> Option<Eui>

Reads an identifier written as sixteen hexadecimal digits.

Arguments

• text - the digits, in either case, with no separators.

Returns

The identifier, or None when the text is not sixteen hexadecimal digits.

pub fn to_hex(&self) -> String

Writes the identifier as sixteen lowercase hexadecimal digits.

Returns

The digits, which is how a network server’s console shows a gateway.

Trait Implementations

impl Clone for Eui

fn clone(&self) -> Eui

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Eui

impl Debug for Eui

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

Formats the value using the given formatter.

impl Default for Eui

fn default() -> Eui

Returns the “default value” for a type.

impl Display for Eui

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

Formats the value using the given formatter.

impl Eq for Eui

impl Hash for Eui

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 Ord for Eui

fn cmp(&self, other: &Eui) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Eui

fn eq(&self, other: &Eui) -> 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 PartialOrd for Eui

fn partial_cmp(&self, other: &Eui) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
