Struct CheckpointNotification 

pub struct CheckpointNotification {
    pub model_path: String,
    pub model_name: String,
    pub version: u64,
    pub saved_at: String,
    pub training_step: u64,
    pub metadata: HashMap<String, String>,
}

A notification emitted by the backward service when a new model checkpoint has been saved to disk.

Fields

model_path: String

Absolute or relative path to the saved checkpoint file.

model_name: String

Human-readable model name / architecture identifier (e.g. "lstm_dqn_v1").

version: u64

Monotonically increasing version number for this checkpoint lineage. Can be used by consumers to skip stale notifications that arrive out of order.

saved_at: String

ISO-8601 / RFC-3339 timestamp of when the checkpoint was saved.

training_step: u64

Training step (gradient step count) at which this checkpoint was produced. 0 if unknown.

metadata: HashMap<String, String>

Optional key-value metadata attached by the producer (e.g. loss, mean Q, learning rate at checkpoint time).

Implementations

impl CheckpointNotification

pub fn new(model_path: impl Into<String>, model_name: impl Into<String>) -> Self

Create a new checkpoint notification with sensible defaults.

version and training_step default to 0; callers should set them explicitly when the information is available.

pub fn with_version(self, version: u64) -> Self

Set the version number.

pub fn with_training_step(self, step: u64) -> Self

Set the training step.

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Insert a metadata key-value pair.

pub fn to_json(&self) -> Result<String, Error>

Serialise to JSON for publishing over Redis.

pub fn from_json(json: &str) -> Result<Self, Error>

Deserialise from a JSON payload received over Redis.

Trait Implementations

fn clone_from(&mut self, source: &Self)

impl Debug for CheckpointNotification

fn fmt(&self, f: &mut Formatter<'_>) -> Result
