Componenta Default Value
========================

[](#componenta-default-value)

Single marker enum for distinguishing an omitted default value from an explicit `null`.

Use it in APIs where `null` is a meaningful caller-provided value and cannot also mean "argument was not provided".

Installation
------------

[](#installation)

```
composer require componenta/default-value
```

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`componenta/di`Uses `DefaultValue::None` in attributes where `null` can be an explicit default.`componenta/config`Useful for APIs that distinguish an omitted fallback from a `null` fallback.Usage
-----

[](#usage)

```
use Componenta\Stdlib\DefaultValue;

function readOption(string $name, mixed $default = DefaultValue::None): mixed
{
    if ($default === DefaultValue::None) {
        return loadRequiredOption($name);
    }

    return loadOptionalOption($name, $default);
}
```

Passing `null` remains explicit:

```
readOption('cache.ttl', null); // default is intentionally null
```

Contract
--------

[](#contract)

`DefaultValue::None` means no default value was provided. It is intentionally a marker, not a container and not a replacement for `Option`/`Maybe` value objects.

When To Use
-----------

[](#when-to-use)

Use this package for function arguments, resolver APIs, config helpers, and factories that need to preserve the difference between:

- no fallback was given
- fallback was given and the fallback is `null`
