Enum Lifetime 

pub enum Lifetime {
    Transient,
    Session,
    Durable,
}

Persistence lifetime policy hint for memory writes.

All hints are advisory — backends MAY ignore them.

Variants

Transient

Persists only within the current turn/step. Never written to durable storage. Use for intermediate reasoning scratchpad data.

Session

Persists for the duration of the session. Discarded when the session ends.

Durable

Persists indefinitely across sessions.

Trait Implementations

impl Clone for Lifetime

fn clone(&self) -> Lifetime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lifetime

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Lifetime

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Lifetime

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
