Description

Possibly convenient facilities for constructing constants.

Synopsis

Documentation

class IsValue a where Source #

If a Haskell type is an instance of IsValue, it means that a value of that type can be converted to a Futhark PrimValue. This is intended to cut down on boilerplate when writing compiler code - for example, you'll quickly grow tired of writing Constant (LogVal True) loc.
