Module prelude 

Prelude for checkpoint module

Structs

Checkpoint

Complete evolution state for checkpointing

CheckpointBuilder

Builder for creating checkpoints

CheckpointManager

Checkpoint manager for automatic saving

CmaEsCheckpointState

CMA-ES checkpoint state

HyperparameterState

Hyperparameter learning state

Enums

AlgorithmState

Algorithm-specific state variants

CheckpointFormat

Format for checkpoint serialization

Constants

CHECKPOINT_VERSION

Current checkpoint format version

DEFAULT_MAX_CHECKPOINT_BYTES

Default cap on the size (in bytes) of a checkpoint file that load_checkpoint will deserialize (EV-48). Files larger than this, and individual length-prefixed fields larger than this, are rejected with a typed error rather than triggering an unbounded allocation.

MIN_SUPPORTED_CHECKPOINT_VERSION

Oldest checkpoint schema version this build can still load (EV-45).

Traits

SnapshotRng

An RNG whose complete internal state can be captured to bytes and restored, enabling bit-identical checkpoint resume.

Functions

load_checkpoint

Load a checkpoint from a file using the default size limit (DEFAULT_MAX_CHECKPOINT_BYTES).

load_checkpoint_with_limit

Load a checkpoint from a file, rejecting inputs larger than max_bytes.

save_checkpoint

Save a checkpoint to a file
