Documentation

A convenience method for the folktale/conversions/result-to-maybe module.

Note that Error values are discarded, since Nothing can't hold a value.

Example:

const Maybe = require('folktale/maybe');
const Result = require('folktale/result');

Maybe.fromResult(Result.Ok(1));
// ==> Maybe.Just(1)

Maybe.fromResult(Result.Error(1));
// ==> Maybe.Nothing()
