(since C++20) | |
The concept indirect_strict_weak_order specifies requirements for algorithms that call strict weak orders as their arguments. The key difference between this concept and std::strict_weak_order is that it is applied to the types that I1 and I2 references, rather than I1 and I2 themselves.
Semantic requirements
F, I1, and I2 model indirect_strict_weak_order only if all concepts it subsumes are modeled.
