Module checkpoint_manager 

Checkpoint pruning and validation for gradient checkpoints.

This module provides CheckpointPruner for retention-policy-based pruning and CheckpointValidator for CRC-32 integrity verification.

Structs

CheckpointPruner

Applies a RetentionPolicy to a collection of CheckpointRecords and determines which records should be deleted.

CheckpointRecord

Metadata about a single gradient checkpoint.

CheckpointValidator

Validates checkpoint data against stored CRC-32 and size metadata.

RetentionPolicy

Configures which checkpoints the CheckpointPruner should keep.

Enums

ValidationError

Errors that can occur during checkpoint validation.

Functions

crc32

Compute the CRC-32 (IEEE polynomial) of data.
