A BinaryTypeTrait is a class template that describes a relationship between its two template type parameters with a std::integral_constant (typically std::bool_constant) specialization.
[edit] Requirements
- DefaultConstructible and CopyConstructible.
- Takes two template type parameters (additional template parameters are optional and allowed).
- Publicly and unambiguously derived from a specialization of std::integral_constant, known as its base characteristic.
- The member names of the base characteristic are not hidden and are unambiguously available.
[edit] Standard library
The following standard library class templates satisfy BinaryTypeTrait:
| (C++11) |
checks if two types are the same (class template) [edit] |
| (C++11) |
checks if a type is a base of the other type (class template) [edit] |
| (C++26) |
checks if a type is a virtual base of the other type (class template) [edit] |
| (C++11)(C++20) |
checks if a type can be converted to the other type (class template) [edit] |
| (C++20) |
checks if two types are layout-compatible (class template) [edit] |
| checks if a type is a pointer-interconvertible (initial) base of another type (class template) [edit] | |
| checks if a type can be invoked (as if by std::invoke) with the given argument types (class template) [edit] | |
| (C++11) |
checks if the specified type supports uses-allocator construction (class template) [edit] |
