Emptiness Rule provides a simple, rule-based **emptiness validation** implementation for the Aegisora ecosystem.

It is built on top of `aegisora/rule-contract` () and follows its strict validation architecture, ensuring consistent and predictable behavior across applications.

---

✨ Features
----------

[](#-features)

- 🔹 Lightweight and minimal dependencies
- 🔹 Validation for **empty** and **non-empty** values
- 🔹 Supports multiple data types (string, array, object, etc.)
- 🔹 Fully compatible with Aegisora validation pipeline
- 🔹 Strict `Context → Result` validation flow
- 🔹 No raw booleans — only structured results
- 🔹 Safe execution via base `Rule` abstraction
- 🔹 Convenient factory methods (`create()`)
- 🔹 Built-in validation of input values

---

📦 Installation
--------------

[](#-installation)

```
composer require aegisora/emptiness-rule
```

---

🚀 Core Concept
--------------

[](#-core-concept)

This package provides validation rules to check whether a value is:

- empty (`EmptyRule`)
- not empty (`NotEmptyRule`)

Validation is performed by:

- receiving a value via `Context`
- checking it against emptiness criteria
- returning a standardized `Result`

---

📐 What is "empty"?
------------------

[](#-what-is-empty)

The following values are considered **empty**:

- `null`
- empty string (`''`)
- empty array (`[]`)
- objects implementing `Countable` with `count() === 0`

The following are **NOT empty**:

- non-empty strings
- non-empty arrays
- numbers (`int`, `float`)
- booleans
- objects (unless `Countable` and empty)

---

🏗️ Basic Usage
--------------

[](#️-basic-usage)

### ✅ Check if value is NOT empty

[](#-check-if-value-is-not-empty)

```
use Aegisora\Rules\Emptiness\NotEmptyRule;
use Aegisora\RuleContract\Models\Context;

$result = NotEmptyRule::create()->validate(Context::create('hello'));

if ($result->isValid()) {
    // value is NOT empty
} else {
    // value is empty
}
```

---

### ❌ Check if value is empty

[](#-check-if-value-is-empty)

```
use Aegisora\Rules\Emptiness\EmptyRule;
use Aegisora\RuleContract\Models\Context;

$result = EmptyRule::create()->validate(Context::create([]));

if ($result->isValid()) {
    // value is empty
} else {
    // value is NOT empty
}
```

---

🧩 Available Rules
-----------------

[](#-available-rules)

```
EmptyRule::create();
NotEmptyRule::create();
```

Both rules:

- accept any value via `Context`
- return a structured `Result`
- follow identical validation logic with inverted outcomes

---

⚠️ Validation Rules
-------------------

[](#️-validation-rules)

Supported input types:

- `null`
- `string`
- `array`
- `int`
- `float`
- `bool`
- `object` (with special handling for `Countable`)

Unsupported types will throw: `Aegisora\RuleContract\Exceptions\InvalidRuleContextException`

---

🏛️ Architecture
---------------

[](#️-architecture)

This package relies on `aegisora/rule-contract` ().

Validation flow:

1. `validate()` is called
2. `Context` is passed in
3. `executeValidate()` runs
4. Value is checked for emptiness
5. Result is determined (valid / invalid)
6. `Result` is returned

All logic is safely encapsulated within the base `Rule` abstraction.
