Getting Started

Hereldar\Results includes an opinionated version of the Result type of Rust. It is not intended to replicate the original type one-to-one, but to allow developers to handle the results in any way they choose.

Use examples

This Result type allows ignoring errors without a try-catch block:

$value = getValue()->or($default);

It also allows throwing the error as a regular exception:

doSomething()->orFail();

Or throwing a custom exception:

doSomething()->orThrow(new MyException());

More complex flows can be handled by concatenating operations:

$record = fetchRecord()
    ->andThen(updateIt(...))
    ->orElse(insertIt(...))
    ->orFail();

And much more:

doSomething()
    ->onFailure(logFailure(...))
    ->onSuccess(logSuccess(...))
    ->onSuccess(doSomethingElse(...));

Installation

Via Composer:

composer require hereldar/results

Development

Run the following commands from the project folder:

make tests
make static-analysis
make coding-standards

To execute:

• A PHPUnit test suite.
• PHPStan and Psalm for static code analysis.
• Easy Coding Standard to fix coding standards.
