Struct StoreContext 

pub struct StoreContext<'a> { /* private fields */ }

The store-backed context for one repo.

Implementations

impl<'a> StoreContext<'a>

pub fn new( conn: &'a Connection, repo_id: &str, semantic: HashMap<String, SemanticVec>, ) -> Self

A context over conn scoped to repo_id, with the query phrases’ vectors for semantic(...) (empty when no provider ran).

pub fn with_rows_root(self, rows: Vec<Value>) -> Self

Serve rows — target-tagged store rows a plan produced — as the oqx::ROWS_ROOT scan (the residual query’s source). Every other root and every relation, intrinsic and row function still hits the store, so the residual sees exactly what a full scan would.

pub fn take_root_failure(&self) -> Option<OqxError>

The store failure a root scan hit during the run, if any. Every other read fails through the engine’s channel (get / call_method return Err); root has none, so it serves an empty scan and leaves the failure here for the runner to report.

Trait Implementations

impl DataContext for StoreContext<'_>

fn root(&self, name: &str) -> Value

Resolve a named root (the from <name> source / directive receiver). Unknown names are Value::Undefined.

fn get(&self, row: &Value, key: &str) -> Result<Value>

Read a property/relation off a row: a bare identifier (field), a .field segment, or a ^field outer reference all come through here, each against exactly the row of the scope it names. An absent property is Ok(Value::Undefined); the engine never looks elsewhere for it.

fn to_rows(&self, value: &Value) -> Vec<Value>

Coerce a relation/source value into rows.

fn identity(&self, row: &Value) -> Value

Identity of a row for follow cycle detection / dedup and for distinct over unprojected rows.

fn call_function(&self, name: &str, args: &[Value]) -> Option<Result<Value>>

Optional custom free function. None = not handled: the engine falls back to the builtin table, then errors if that has no such function.

fn call_method( &self, name: &str, recv: &Value, args: &[Value], ) -> Option<Result<Value>>

Optional custom method (recv.name(args)). None = not handled, as for DataContext::call_function.

fn regex_dialect(&self) -> RegexDialect

The regex dialect matches() compiles against. RegexDialect::Oqx (the default) is the portable baseline the spec tests; RegexDialect::Native hands the pattern to the regex crate as is — implementation-defined, not portable. The engine dispatches matches through DataContext::call_method, so this is read by the context’s own matches (DefaultContext does, via crate::semantics::builtin_method_with); plain crate::semantics::builtin_method is always the baseline.
