Binary-operator vocabulary.
BinOp is the syntactic binary-operator enum the query AST emits and
the coercion spine keys overload resolution on. It is coercion
vocabulary as much as it is parser vocabulary: the spine
(coercion_spine::resolve_binop) cannot resolve an operator overload
without it, and that spine lives in this keystone crate (ADR 0052).
Re-homing only the spine while leaving BinOp in the server would force
this crate to depend back on reddb-server — the exact cycle ADR 0052
exists to prevent. So the operator vocabulary moves here and the query
AST in reddb-rql imports it directly, keeping one operator definition.
The move is byte-faithful: the enum, its variant set, and the
precedence() table was relocated verbatim from the former server AST.
Enums§
- BinOp
- Syntactic binary operators. Parsed precedence determines grouping;
this enum only identifies the operator itself. Comparison and logical
operators live alongside arithmetic so a single
Expr::BinaryOpwalker can cover every infix form the parser emits.
