Witch.TryFrom

Documentation

class TryFrom source target where

This type class is for converting values from some source type into some other target type. The constraint TryFrom source target means that you may be able to convert from a value of type source into a value of type target, but that conversion may fail at runtime.

This type class is for conversions that can sometimes fail. If your conversion always succeeds, consider implementing From instead.

Methods

tryFrom :: source -> Either (TryFromException source target) target

This method implements the conversion of a value between types. At call sites you may want to use tryInto instead.

-- Avoid this:
tryFrom (x :: s)

-- Prefer this:
tryFrom @s

Consider using maybeTryFrom or eitherTryFrom to implement this method.
