Refined.Unsafe.Type

Description

This module exports the Refined type with its constructor. This is very risky! In particular, the Coercible instances will be visible throughout the importing module. It is usually better to build the necessary coercions locally using the utilities in Refined.Unsafe, but in some cases it may be more convenient to write a separate module that imports this one and exports some large coercion.

Synopsis

newtype Refined p x = Refined x

Documentation

newtype Refined p x Source #

A refinement type, which wraps a value of type x, ensuring that it satisfies a type-level predicate p.

Constructors

Refined x
