Struct CheckpointMetadata 

pub struct CheckpointMetadata {
    pub thread_id: String,
    pub checkpoint_id: String,
    pub run_id: Option<String>,
    pub parent_checkpoint_id: Option<String>,
    pub namespace: Vec<String>,
    pub next_nodes: Vec<NodeId>,
    pub has_interrupts: bool,
    pub source: CheckpointSource,
    pub step: usize,
}

Lightweight checkpoint summary returned by Checkpointer::list.

Listing must not require deserializing full graph state, so metadata is kept separate from the Checkpoint state payload.

Fields

thread_id: String

Thread lineage key.

checkpoint_id: String

Checkpoint id.

run_id: Option<String>

The run that produced this checkpoint, when known.

parent_checkpoint_id: Option<String>

Parent checkpoint id.

namespace: Vec<String>

Namespace scoping.

next_nodes: Vec<NodeId>

Nodes to run on resume.

has_interrupts: bool

Whether the checkpoint carries pending interrupts.

source: CheckpointSource

Checkpoint source: input, loop, update, or fork.

step: usize

The superstep number that produced the checkpoint.
