projected

helper template for specifying the constraints on algorithms that accept projections More...

Detailed Description

projected is used only to constrain algorithms that accept callable objects and projections, and hence its operator*() is not defined.

Warning

vccc::projected meets the requirements of C++ 26, but without using constraints user must check its validity with vccc::projectable<I, Proj>before using vccc::projected
