README

Meant to be a drop-in replacement for nikita2206/result, with one addition: wrap().

wrap() was inspired by github.com/pkg/errors.

Installation

composer require dxw/result 

Usage

Returning values:

function myfunc(): \Dxw\Result\Result { if (/* error */) { // getErr() will return 'something went wrong' return \Dxw\Result\Result::err('something went wrong'); } return \Dxw\Result\Result::ok($value); } 

Handling Result values:

$result = myfunc(); if ($result->isErr()) { echo sprintf("Error: %s\n", $result->getErr()); exit(1); } $value = $result->unwrap(); 

Returning errors from other errors:

function anotherfunc(): \Dxw\Result\Result { $result = myfunc(); if ($result->isErr()) { // getErr() will return 'got invalid value: something went wrong' return $result->wrap('got invalid value'); } // do something with $result->unwrap() }
