Assert Laravel Package

beberlei/assert is a lightweight PHP library that provides assertions and guard methods for input validation (not filtering) in business models, libraries, and low-level application code. It implements pre- and post-conditions on input data, throwing an exception whenever an assertion fails—eliminating boilerplate if-clauses and simplifying your code paths.

Unlike Symfony or Zend validators, the checks are deliberately low-level, fast, and non-object-oriented, requiring no object instantiation, locale component, or translations.

• Simple, expressive API: Assertion::file(), Assertion::digit(), and many more
• Exception-driven failures remove manual conditional checks
• Minimal dependencies and near-zero overhead
• Installable via Composer: composer require beberlei/assert
