Clash.Core.PartialEval.Monad

Description

The monad for partial evaluation, and its API. This should contain all auxiliary functions needed to define new evaluator implementations. This module is only needed to define new evaluators, for calling an existing evaluator see Clash.Core.PartialEval.

Synopsis

Partial Evaluation Monad

data Eval a Source #

The monad of partial evaluation. The inner monad is IO, as primitive evaluation can attempt to evaluate IO actions.
