Struct Persisted 

pub struct Persisted<T> { /* private fields */ }

A wrapper for @persistent fields that auto-checkpoints on modification.

This provides interior mutability and automatic persistence when the value is modified via set().

Implementations

impl<T: Clone + Serialize + DeserializeOwned + Default + Send> Persisted<T>

pub fn new( store: Arc<dyn CheckpointStore>, agent_key: impl Into<String>, field_name: impl Into<String>, ) -> Self

Create a new persisted field, loading from checkpoint if available.

pub fn with_initial( store: Arc<dyn CheckpointStore>, agent_key: impl Into<String>, field_name: impl Into<String>, initial: T, ) -> Self

Create with an explicit initial value (used when no checkpoint exists).

pub fn get(&self) -> T

Get the current value.

pub fn set(&self, new_value: T)

Set the value and checkpoint it.

pub fn checkpoint(&self)

Checkpoint the current value without modifying it.
