Interface PHPStan\Reflection\Callables\CallableParametersAcceptor

`extends`	`ParametersAcceptor`

A ParametersAcceptor for callable types (closures, first-class callables). Extends ParametersAcceptor with information about side effects, exceptions, and other runtime behavior of callable values. This is what PHPStan knows about a closure or callable when it's passed as a parameter or stored in a variable. Implemented by ClosureType and used as the return type of Type::getCallableParametersAcceptors(). Provides:

Throw points (what exceptions the callable may throw)
Impure points (what side effects the callable may have)
Purity information
Variables captured from outer scope (used variables)
Expressions that are invalidated by calling this callable
