Struct Codes 

pub struct Codes<T>(/* private fields */);

Re-export common protocol types and payload handlers The Codes module provides a generic structure to handle a collection of MQTT return codes. These codes are used in various MQTT control packets, such as ConnAck, SubAck, and UnsubAck.

Example

use mqute_codec::protocol::{Codes, QoS};
use mqute_codec::protocol::v4::ReturnCode;

let values = vec![ReturnCode::Failure, ReturnCode::Success(QoS::AtLeastOnce)];
let codes: Codes<ReturnCode> = Codes::new(values);
assert_eq!(codes.len(), 2);

Implementations

impl<T> Codes<T>

where T: TryFrom<u8, Error = Error> + Into<u8> + Copy,

pub fn new<I: IntoIterator<Item = T>>(codes: I) -> Self

Creates a new Codes instance from an iterator of codes.

Panics

Panics if the iterator is empty, as at least one code is required.

pub fn len(&self) -> usize

Returns the number of codes in the Codes instance.

Trait Implementations

impl<T> AsRef<Vec<T>> for Codes<T>

fn as_ref(&self) -> &Vec<T>

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Borrow<Vec<T>> for Codes<T>

fn borrow(&self) -> &Vec<T>

Immutably borrows from an owned value.

impl<T: Clone> Clone for Codes<T>

fn clone(&self) -> Codes<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Codes<T>

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

Formats the value using the given formatter.

impl<T> From<Codes<T>> for Vec<T>

fn from(value: Codes<T>) -> Self

Converts to this type from the input type.

impl<T> From<Vec<T>> for Codes<T>

fn from(value: Vec<T>) -> Self

Converts to this type from the input type.

impl<T> FromIterator<T> for Codes<T>

fn from_iter<I: IntoIterator<Item = T>>(iter: I) -> Self

Creates a value from an iterator.

impl<T> Index<usize> for Codes<T>

type Output = T

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T> IndexMut<usize> for Codes<T>

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<T> IntoIterator for Codes<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: PartialEq> PartialEq for Codes<T>

fn eq(&self, other: &Codes<T>) -> 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.
