Implementations

impl SqliteStore

pub fn open(db_path: &Path) -> Result<Self>

Open an existing ledger.db.

pub fn open_or_create(db_path: &Path) -> Result<Self>

Open or create ledger.db with full schema.

pub fn append_event(&self, event: &Event) -> Result<()>

Append an event. Append-only (CONTRACT LEDGER-02).

If the event is a decision (note with "decision" tag), the decisions table is also updated atomically within the same transaction.

pub fn iter_events(&self) -> Result<Vec<Event>>

Read all events in insertion order.

pub fn last_event_hash(&self) -> Result<Option<String>>

Get the hash of the last event.

pub fn head_branch(&self) -> Result<String>

Read the current HEAD branch name.

pub fn set_head_branch(&self, name: &str) -> Result<()>

Write the HEAD branch name.

pub fn branches_json(&self) -> Result<Value>

Read branches.json equivalent from refs table.

pub fn set_branches_json(&self, value: &Value) -> Result<()>

Write branches.json equivalent to refs table.

pub fn active_decisions( &self, domain: Option<&str>, key_pattern: Option<&str>, ) -> Result<Vec<DecisionRow>>

Query active decisions, optionally filtered by domain or key prefix.

pub fn decision_timeline(&self, key: &str) -> Result<Vec<DecisionRow>>

All decisions for a key (active + superseded), ordered by time.

pub fn domain_timeline(&self, domain: &str) -> Result<Vec<DecisionRow>>

All decisions for a domain (active + superseded), ordered by time.

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

Distinct domain values from active decisions.

pub fn find_active_decision( &self, branch: &str, key: &str, ) -> Result<Option<DecisionRow>>

Find the active decision for a specific key on a branch.
