Implementations

impl Store

pub fn open(target: &str) -> Result<Self>

Open target: a postgres:// / postgresql:// URL with ?model= opens that Postgres model; anything else is a Mentat file path ("" is in-memory).

pub fn load_model(&mut self) -> Result<Model>

pub fn load_partial(&mut self, measure_ids: &[MeasureId]) -> Result<Model>

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

pub fn reload_model(&mut self) -> Result<Model>

pub fn tx_high_water(&mut self) -> Result<i64>

pub fn loaded_tx(&self) -> Option<i64>

pub fn set_loaded_tx(&mut self, tx: Option<i64>)

pub fn save_token(&self) -> SaveToken

Everything a later handle needs to save safely over what this one loaded or saved: the optimistic-concurrency token and (Postgres) the snapshot a save diffs against, so it writes only what changed. Callers that reopen the store per save carry this across handles.

pub fn set_save_token(&mut self, token: &SaveToken)

Adopt a token from Store::save_token before saving.
