The Simple Result Type
======================

[](#the-simple-result-type)

[![Testing](https://github.com/takemo101/simple-result-type/actions/workflows/testing.yml/badge.svg)](https://github.com/takemo101/simple-result-type/actions/workflows/testing.yml)[![PHPStan](https://github.com/takemo101/simple-result-type/actions/workflows/phpstan.yml/badge.svg)](https://github.com/takemo101/simple-result-type/actions/workflows/phpstan.yml)[![Validate Composer](https://github.com/takemo101/simple-result-type/actions/workflows/composer.yml/badge.svg)](https://github.com/takemo101/simple-result-type/actions/workflows/composer.yml)

The Simple Result Type simply returns the processing result as an object.
Enjoy!

Example
-------

[](#example)

This is a basic usage example.

```
use Takemo101\SimpleResultType\ {
    Resulter,
    Error,
    Success,
};
use Exception;

// Create a Success object with the Success method of the Resulter class.
$data = Resulter::success(10)
    // Create a Result object with a new value by the map method.
    ->map(fn(int $result) => $result * 2)
    // Get the success result by the success method.
    ->success();

var_dump($data); // int(20)

// Create an Error object with the error method of the Resulter class.
$data = Resulter::error(10)
    // Create an Error object with a new value by the mapError method.
    ->mapError(fn(int $result) => $result * 2)
    // Get the error result by the error method.
    ->error();

var_dump($data); // int(20)

// If you generate an Error with a value that implements Throwable,
// an exception will be raised.
Resulter::error(new Exception('error'))
    ->exception();

// You can get the output according to the result by the output method.
$data = Resulter::success(10)
    ->map(fn(int $result) => $result * 2)
    ->output(
        success: fn(int $result) => $result * 100,
        error: fn(int $result) => $result * 1,
    );

var_dump($data); // int(2000)
```

This is an example of using to determine whether the result is success or error.

```
use Takemo101\SimpleResultType\ {
    Error,
    Success,
};

// You can also create objects from the Error and Success classes.
$result = Error::create('error');

var_dump($result->isError()); // bool(true)
var_dump($result->isSuccess()); // bool(false)

$result = Success::create('success');

// You can also judge by Type enum.
$data = match ($result->type()) {
    Type::Success => $result->success(),
    Type::Error => $result->error(),
};

var_dump($data); // string(7) "success"
```

Try operations that may fail and produce results.

```
use Takemo101\SimpleResultType\Resulter;
use Takemo101\SimpleResultType\Support\ {
    CatchType,
    NotCatchType,
};
use Exception;
use LogicException;
use RuntimeException;
use InvalidArgumentException;

// If an exception occurs, the result will be returned as Error.
$result = Resulter::try(function() {
    throw new Exception('error');
}); // Error

// By returning the success value, the result will be returned as Success.
$result = Resulter::try(function() {
    return 10;
}); // Success

// No error is output except for the exception specified in the CatchType Attribute class.
$result = Resulter::try(
    #[CatchType(
        RuntimeException::class,
        InvalidArgumentException::class,
    )]
    function() {
        throw new RuntimeException('error');
    }
); // Error

var_dump($result->isError()); // bool(true)

// No error is output for the exception specified in the NotCatchType Attribute class.
Resulter::try(
    #[NotCatchType(
        RuntimeException::class,
        InvalidArgumentException::class,
    )]
    function() {
        throw new RuntimeException('error');
    }
); // Exception occurs.
```

Exception handling by ErrorHandler class.

```
use Takemo101\SimpleResultType\Resulter;
use Takemo101\SimpleResultType\Support\ErrorHandler;
use LogicException;
use RuntimeException;

// If an exception occurs, the Error wrapped in the ErrorHandler class is returned.
$result = Resulter::trial(function() {
    throw new RuntimeException('error');
}); // Error

// ErrorHandler can be used for processing according to the type of exception
$data = $result->error()
    ->catch(fn (RuntimeException $e) => $e->getMessage())
    ->catch(fn (LogicException $e) => $e->getMessage())
    ->exception(); // or ->call();

var_dump($data); // string(5) "error"
```
