Enum async_nats::jetstream::stream::DiscardPolicy

#[repr(u8)]
pub enum DiscardPolicy {
    Old,
    New,
}

DiscardPolicy determines how we proceed when limits of messages or bytes are hit. The default, Old will remove older messages. New will fail to store the new message.

Variants

Old

will remove older messages when limits are hit.

New

will error on a StoreMsg call when limits are hit

Trait Implementations

impl Clone for DiscardPolicy

fn clone(&self) -> DiscardPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DiscardPolicy

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

Formats the value using the given formatter.

impl Default for DiscardPolicy

fn default() -> DiscardPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DiscardPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<DiscardPolicy> for DiscardPolicy

fn eq(&self, other: &DiscardPolicy) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DiscardPolicy

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

Serialize this value into the given Serde serializer.
