Module ops 

The closed exact-operator registries rustev.exact/1 (spec 002, 3.8) and rustev.exact/2 (spec 032, 3.5 and 3.6), which adds join_keyed@1 and merge_fields@1 with every rustev.exact/1 operator unchanged.

An operator is named with a version. Changing what an operator means is a new version, never an edit (E-06). Each operator’s arguments are decoded strictly against its own schema.

Functions

decode

Decode the arguments of a registered operator; None when (op, version) is not registered (refusal category 2, not a parse failure).

decode_v2

is_registered

is_registered_v2

Whether (op, version) is in rustev.exact/2.
