Struct DistributedCheckpoint 

#[non_exhaustive]
pub struct DistributedCheckpoint {
    pub checkpoint_dir: PathBuf,
    pub shard_metadata: ShardMetadata,
}

Handle for a distributed checkpoint directory.

Wraps the directory path and the shard metadata. Typically created by save_distributed (which writes files) or by reading an existing checkpoint’s metadata.json.

Marked #[non_exhaustive] for forward-compatible additions (e.g., async-write handles, optimizer-state cache).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

checkpoint_dir: PathBuf

Directory where shard files are stored.

shard_metadata: ShardMetadata

Metadata about how tensors are sharded across ranks.
