Version 1.x
Introduction
Version 1 was written to replace ganbarodigital/php-defensive. It offers pretty much the same functionality as that library did, just with an improved interface.
Key Ideas
The key ideas in Version 1 are:
- requirements (checks on inputs) and assurances (checks on outputs and return values)
Assurance::apply()->to()/Requirement::apply()->to()pattern - apply the assurance / requirement to a value. If the assurance / requirement isn't met, throw an exception.ListAssurance::apply()->toList()/ListRequirement::apply()->toList()pattern - apply the assurance / requirement to a list of values. If the assurance / requirement isn't met, throw an exception.- composable assurances and requirements - each
Assurance/Requirementnow takes one parameter (the value being checked). This allows us to build lists of assurances / requirements to apply to a value.
