Keysets

define-keyset

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.

(define-keyset 'admin-keyset (read-keyset "keyset"))

(define-keyset 'admin-keyset (read-keyset "keyset"))

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

enforce-keyset

guard guard → bool

keysetname string → bool

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

(enforce-keyset 'admin-keyset)
(enforce-keyset row-guard)

(enforce-keyset 'admin-keyset)
(enforce-keyset row-guard)

keys-2

count integer matched integer → bool

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

pact> (keys-2 3 1)
false

pact> (keys-2 3 1)
false

keys-all

count integer matched integer → bool

Keyset predicate function to match all keys in keyset.

pact> (keys-all 3 3)
true

pact> (keys-all 3 3)
true

keys-any

count integer matched integer → bool

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

pact> (keys-any 10 1)
true

pact> (keys-any 10 1)
true

read-keyset

key string → keyset

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

(read-keyset "admin-keyset")

(read-keyset "admin-keyset")
