Enum RetentionPolicy

#[repr(u8)]
pub enum RetentionPolicy {
    Limits = 0,
    Interest = 1,
    WorkQueue = 2,
}

RetentionPolicy determines how messages in a set are retained.

Variants

Limits = 0

Limits (default) means that messages are retained until any given limit is reached. This could be one of messages, bytes, or age.

Interest = 1

Interest specifies that when all known observables have acknowledged a message it can be removed.

WorkQueue = 2

WorkQueue specifies that when the first worker or subscriber acknowledges the message it can be removed.

Trait Implementations

impl Clone for RetentionPolicy

fn clone(&self) -> RetentionPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RetentionPolicy

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

Formats the value using the given formatter.

impl Default for RetentionPolicy

fn default() -> RetentionPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RetentionPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RetentionPolicy

fn eq(&self, other: &RetentionPolicy) -> 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 Serialize for RetentionPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
