Collection of value objects that represent the types of PHP Extended Type System. Currently, all the types are inspired by popular PHP static analysis tools: Psalm and PHPStan.
All implementations of Type should be treated as sealed, Type interface MUST NOT be implemented in userland!
If you need an alias for a complex compound type, extend TypeAlias.
This library will never have any dependencies. Once full and stable, it might be proposed as a PSR or PER.
composer require extended-type-system/type
Value objects, representing native PHP types cannot be named after them, because words like Int, Strind etc. are reserved.
A suffix might be introduced to fix this problem. Type suffix is too verbose, so we have chosen T: int -> IntT, float -> FloatT.
Although types like non-empty-list can be safely named NonEmptyList, for now we have decided to follow the T-convention for all types.
