Struct ModelCatalog 

pub struct ModelCatalog { /* private fields */ }

In-memory model catalog keyed by (measurement, model_name).

Thread Safety

ModelCatalog is not internally synchronised. The server wraps it in Arc<RwLock<ModelCatalog>> (see AppState::model_catalog), which provides correct concurrent access. This is intentional: embedding a lock would impose overhead on single-threaded forecast pipelines and prevents read-side parallelism that RwLock provides.

Implementations

impl ModelCatalog

pub fn new() -> Self

Creates an empty catalog.

pub fn save_model<M: ModelStore>( &mut self, measurement: &str, name: &str, model: &M, model_type: ModelType, training_range: (i64, i64), training_points: usize, mse: f64, mae: f64, r_squared: f64, ) -> Result<ModelMetadata, StorageError>

Saves a model to the catalog.

If a model with the same (measurement, name) already exists the version is auto-incremented.

pub fn load_model<M: ModelStore>( &self, measurement: &str, name: &str, ) -> Result<M, StorageError>

Loads a model from the catalog, deserializing it.

pub fn get_metadata( &self, measurement: &str, name: &str, ) -> Option<&ModelMetadata>

Returns metadata for a stored model (if it exists).

pub fn list_models(&self, measurement: &str) -> Vec<&ModelMetadata>

Lists metadata for all models under a given measurement.

pub fn list_all(&self) -> Vec<&ModelMetadata>

Lists metadata for all models in the catalog.

pub fn delete_model(&mut self, measurement: &str, name: &str) -> bool

Deletes a model from the catalog.

Trait Implementations

impl Debug for ModelCatalog

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

impl Default for ModelCatalog

fn default() -> ModelCatalog

Returns the “default value” for a type.
