Struct RegistryDb 

pub struct RegistryDb { /* private fields */ }

SQLite database for registry metadata.

Implementations

impl RegistryDb

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Open or create a database at the given path.

Errors

Returns an error if the database cannot be opened.

pub fn vacuum_into<P: AsRef<Path>>(&self, target: P) -> Result<()>

HELIX-IDEA-007 — atomic point-in-time snapshot via SQLite VACUUM INTO 'path'. The target path MUST NOT already exist; SQLite refuses to overwrite, and we surface that refusal as PachaError::Database rather than silently truncating.

Concurrent writers continue against the source DB; their changes are not visible in the snapshot. Reads block briefly only while VACUUM INTO copies pages.

Contract: contracts/apr-registry-snapshot-v1.yaml (FALSIFY-SNAPSHOT-001..003).

Errors

Returns an error if the SQL fails — most commonly when target already exists.

pub fn insert_model(&self, model: &Model) -> Result<()>

Insert a model into the database.

pub fn model_exists(&self, name: &str, version: &ModelVersion) -> Result<bool>

Check if a model exists.

pub fn get_model(&self, name: &str, version: &ModelVersion) -> Result<Model>

Get a model by name and version.

pub fn get_model_by_id(&self, id: &ModelId) -> Result<Model>

Get a model by ID.

pub fn list_model_versions(&self, name: &str) -> Result<Vec<ModelVersion>>

List all versions of a model.

pub fn list_model_names(&self) -> Result<Vec<String>>

List all model names.

pub fn update_model_stage(&self, id: &ModelId, stage: ModelStage) -> Result<()>

Update model stage.

pub fn count_models(&self) -> Result<usize>

Count models.

pub fn insert_dataset(&self, dataset: &Dataset) -> Result<()>

Insert a dataset into the database.

pub fn dataset_exists( &self, name: &str, version: &DatasetVersion, ) -> Result<bool>

pub fn count_recipes(&self) -> Result<usize>

Count recipes.

pub fn insert_run(&self, run: &ExperimentRun) -> Result<()>

Insert an experiment run.

pub fn update_run(&self, run: &ExperimentRun) -> Result<()>

Update an experiment run.

pub fn get_run(&self, run_id: &RunId) -> Result<ExperimentRun>
