Lorentz.Zip

Stack zipping.

This module provides functions for flattening stacks into tuples.

Also here we define an instance which turns any instruction, not only lambdas, into a valid value.

Documentation

class KnownIsoT (ZippedStack s) => ZipInstr (s :: [Type]) where

Zipping stack into tuple and back.

Associated Types

type ZippedStack s :: Type

A type which contains the whole stack zipped.

Methods

zipInstrTyped :: Instr (ToTs s) '[ToT (ZippedStack s)]

Fold given stack into single value in typed Michelson.

unzipInstrTyped :: Instr '[ToT (ZippedStack s)] (ToTs s)

Unfold given stack from a single value in typed Michelson.

Instances

ZipInstr ('[] :: [Type])

Defined in Lorentz.Zip

Associated Types

type ZippedStack '[]

Methods

zipInstrTyped :: Instr (ToTs '[]) '[ToT (ZippedStack '[])]

unzipInstrTyped :: Instr '[ToT (ZippedStack '[])] (ToTs '[])

(ZipInstr (b ': s), KnownIsoT a) => ZipInstr (a ': (b ': s))

Such definition seems the only possible one we can support efficiently.
