Detailed Description

struct Chusov::Math::is_satisfied_by_one< predicate, T >

Checks if at least one type in a pack satisfies a specified compile-time predicate.

Template Parameters

predicate	is a template which consequently receives types of the pack T. It must provide a compile-time constant value of thebool type to reflect the property of types of the pack to check. The predicate must be unary.
T	is a type parameter pack.

As a result, the class is_satisfied_by_one inherits from either std::true_type or std::false_type, depending on a value produced by logical_or for values obtained by applying the predicate to the types of the pack T.
