Struct CheckpointData 

pub struct CheckpointData<S: StateSchema> {
    pub id: String,
    pub state: S,
    pub timestamp: i64,
    pub metadata: HashMap<String, Value>,
    pub seq: u64,
    pub recursion_count: usize,
}

Checkpoint data structure

Fields

id: String

state: S

timestamp: i64

metadata: HashMap<String, Value>

seq: u64

Monotonic sequence number assigned by the checkpointer on save. Breaks ties between checkpoints saved within the same timestamp second, so “most recent” is well-defined even for fast back-to-back saves (H5).

recursion_count: usize

Recursion budget consumed when this checkpoint was taken, so a resume continues counting against the same recursion_limit instead of restarting from zero (M6).

Implementations

impl<S: StateSchema> CheckpointData<S>

pub fn new(state: S) -> Self

pub fn with_progress(state: S, seq: u64, recursion_count: usize) -> Self

Construct with the checkpointer-assigned sequence and the run’s current recursion budget.

Trait Implementations
