Struct EchoId

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

Echo message “identifier” field.

Examples

Constructing from a u16 with big-endian byte ordering:

use async_icmp::message::echo::EchoId;

let id: EchoId = EchoId::from_be(123);

Generating a random id via the rand Distribution impl (enabled via the rand feature):

use async_icmp::message::echo::EchoId;

let id: EchoId = rand::random();

Implementations

impl EchoId

pub fn from_be(num: u16) -> Self

Construct an id from the big-endian bytes of num.

pub fn from_le(num: u16) -> Self

Construct an id from the little-endian bytes of num.

pub fn as_array(&self) -> [u8; 2]

Returns the id as a byte array.

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

Returns the id as a length-2 slice.

pub fn as_be(&self) -> u16

Returns the bytes interpreted as big-endian

pub fn as_le(&self) -> u16

Returns the bytes interpreted as little-endian

Trait Implementations

impl Clone for EchoId

fn clone(&self) -> EchoId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EchoId

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

Formats the value using the given formatter.

impl Distribution<EchoId> for Standard

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> EchoId

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl From<[u8; 2]> for EchoId

fn from(value: [u8; 2]) -> Self

Converts to this type from the input type.

impl Hash for EchoId

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 EchoId

fn eq(&self, other: &EchoId) -> 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.
