Documentation
newtype StepCounter (n ∷ Nat) s Source #
A set of Word8 counters that is used in the CEK machine
to count steps.
Constructors

newCounter ∷ (KnownNat n, PrimMonad m) ⇒ Proxy n → m (StepCounter n (PrimState m)) Source #
Make a new StepCounter with the given number of counters.
resetCounter ∷ ∀ n m. (KnownNat n, PrimMonad m) ⇒ StepCounter n (PrimState m) → m () Source #
Reset all the counters in the given StepCounter to zero.
readCounter ∷ ∀ m n. PrimMonad m ⇒ StepCounter n (PrimState m) → Int → m Word8 Source #
Read the value of a counter.
writeCounter ∷ ∀ m n. PrimMonad m ⇒ StepCounter n (PrimState m) → Int → Word8 → m () Source #
