Test.Cardano.Ledger.Shelley.Generator.TxCert

Synopsis

Documentation

genTxCert ∷ ∀ era. (EraGen era, ProtVerAtMost era 8) ⇒ ConstantsKeySpace era → PParams era → AccountStateCertState era → SlotNoGen (Maybe (TxCert era, CertCred era)) Source #

Occasionally generate a valid certificate

Returning Nothing indicates a failure to generate a value, usually due to lack of available values from the pre-populated (e.g. key) spaces. A Just represents a successfully generated value.

Different generators return witnesses that are either genesis or regular keys.

Note: we register keys and pools more often than deregistering/retiring them, and we generate more delegations than registrations of keys/pools.
