Enum QoSReliabilityPolicy

pub enum QoSReliabilityPolicy {
    SystemDefault = 0,
    Reliable = 1,
    BestEffort = 2,
}

The RELIABILITY DDS QoS policy.

This policy determines whether delivery between a publisher and a subscription will be retried until successful, or whether messages may be lost in a trade off for better performance.

Compatibility

Publisher	Subscription	Compatible	Behavior
Reliable	Reliable	yes	Reliable
Reliable	BestEffort	yes	Best effort
BestEffort	Reliable	no	-
BestEffort	BestEffort	yes	Best effort

Variants

SystemDefault = 0

Use the default policy of the RMW layer.

Reliable = 1

Guarantee delivery of messages.

BestEffort = 2

Send messages but do not guarantee delivery.

Trait Implementations

impl Clone for QoSReliabilityPolicy

fn clone(&self) -> QoSReliabilityPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QoSReliabilityPolicy

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

Formats the value using the given formatter.

impl Ord for QoSReliabilityPolicy

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

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

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