Keysets

name string keyset string → string

name string → string

Define keyset as NAME with KEYSET, or if unspecified, read NAME from message payload as keyset, similarly to 'read-keyset'. If keyset NAME already exists, keyset will be enforced before updating to new value.

Top level only: this function will fail if used in module code.

guard guard → bool

keysetname string → bool

Execute GUARD, or defined keyset KEYSETNAME, to enforce desired predicate logic.

count integer matched integer → bool

Keyset predicate function to match at least 2 keys in keyset.

count integer matched integer → bool

Keyset predicate function to match all keys in keyset.

count integer matched integer → bool

Keyset predicate function to match any (at least 1) key in keyset.

key string → keyset

Read KEY from message data body as keyset ({ "keys": KEYLIST, "pred": PREDFUN }). PREDFUN should resolve to a keys predicate.
