Trait Implementations

impl Clone for QoS

fn clone(&self) -> QoS

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QoS

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

Formats the value using the given formatter.

impl Default for QoS

fn default() -> QoS

Returns the “default value” for a type.

impl Display for QoS

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

Formats the value using the given formatter.

impl From<QoS> for ConnectFlags

fn from(qos: QoS) -> ConnectFlags

Converts to this type from the input type.

impl From<QoS> for u8

fn from(val: QoS) -> u8

Converts to this type from the input type.

impl Ord for QoS

fn cmp(&self, other: &QoS) -> 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 QoS

fn eq(&self, other: &QoS) -> 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 QoS

fn partial_cmp(&self, other: &QoS) -> 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.

impl TryFrom<u8> for QoS

type Error = Error

The type returned in the event of a conversion error.

fn try_from(val: u8) -> Result<QoS>

Performs the conversion.
