Enum QoS

pub enum QoS {
    BestEffort,
    Reliable,
    Guaranteed,
    RealTime,
}

Quality of Service (QoS) levels for message delivery

Variants

BestEffort

Best effort delivery - messages may be dropped under pressure

Reliable

Reliable delivery - oldest messages dropped when buffer full

Guaranteed

Guaranteed delivery - error returned when buffer full

RealTime

Real-time delivery - newest messages overwrite oldest when buffer full

Implementations

impl QoS

pub fn as_str(&self) -> &'static str

Get string representation of QoS level

Trait Implementations

impl Clone for QoS

fn clone(&self) -> QoS

Returns a duplicate 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<(), Error>

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 Hash for QoS

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 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 Copy for QoS

impl Eq for QoS

impl StructuralPartialEq for QoS
