Struct OptimizerRecord 

pub struct OptimizerRecord { /* private fields */ }

A serialized optimizer state, stored in the burnpack format.

Unlike a module record (keyed by module path), an optimizer record is keyed per parameter: each parameter’s state is decomposed into tensors named "{param_id}.{field}" (carrying the originating param_id) plus a few typed scalar entries kept in the burnpack scalar map.

Obtain one from a ModuleOptimizer with to_record, then save it (save / into_bytes) or apply it back with load_record.

Implementations

impl OptimizerRecord

pub fn len(&self) -> usize

The number of tensors in the record.

pub fn is_empty(&self) -> bool

Whether the record holds no tensors.

pub fn into_bytes(self) -> Result<Bytes, RecordError>

Serialize the record to an in-memory burnpack byte buffer.

pub fn from_bytes(bytes: Bytes) -> Result<OptimizerRecord, RecordError>

Reconstruct a record from an in-memory burnpack byte buffer.

pub fn save<P>(self, path: P) -> Result<(), RecordError>

where P: AsRef<Path>,

Save the record to a burnpack file on disk.

pub fn load<P>(path: P) -> Result<OptimizerRecord, RecordError>

where P: AsRef<Path>,

Load a record from a burnpack file on disk.
