Struct Database 

pub struct Database<S> { /* private fields */ }

Owns the graph store and orchestrates parse → analyze → compile → execute.

Implementations

impl Database<InMemoryGraph>

pub fn in_memory() -> Self

Convenience constructor: a fresh, empty in-memory graph database.

impl<S> Database<S>

where S: GraphStorage + GraphStorageMut,

pub fn new(store: Arc<Mutex<S>>) -> Self

Build a database from a pre-wrapped, shared store.

pub fn from_graph(graph: S) -> Self

Build a database by taking ownership of a bare graph store.

pub fn store(&self) -> &Arc<Mutex<S>>

Handle to the underlying shared store — useful for callers that need to snapshot or share the graph across multiple databases.

pub fn parse(&self, query: &str) -> Result<Document>

Parse a query string into an AST without executing it.

pub fn execute( &self, query: &str, options: Option<ExecuteOptions>, ) -> Result<QueryResult>

Execute a query and return its result.

pub fn execute_with_params( &self, query: &str, options: Option<ExecuteOptions>, params: BTreeMap<String, LoraValue>, ) -> Result<QueryResult>

Execute a query with bound parameters.
