Implementations

impl Stmt

pub fn stmt_kind(&self) -> &'static str

Return the canonical keyword name for this statement variant (e.g. “QUERY”, “CREATE COLLECTION”).

impl Stmt

pub fn shard_key(&self) -> Option<&ShardKey>

Custom shard routing key for this statement, if any.

Corresponds to QQL SHARD on DML, lowered to request-level shard_key (REST) / ShardKeySelector (gRPC) — never inside Filter. Keyword and numeric forms are preserved (ShardKey::Number(101) reads back as a number, never coerced to "101").

pub fn set_shard_key(&mut self, shard_key: Option<ShardKey>) -> bool

Set custom shard routing (same field as QQL SHARD).

Prefer writing the SHARD clause in the query when the tenant is known at authoring time. Use this setter only when the host resolves the key after parse (e.g. from auth context) without re-stringifying QQL.

On QUERY, recurses into CTEs and nested prefetch queries so routing matches a top-level SHARD clause. None (or an empty keyword) clears the key. Returns false for statement types that cannot carry routing (DDL, SHOW).
