Function Documentation

MakeSpan() [1/2]

template<typename A , int N>

constexpr Span<A> MakeSpan

(

A(&)

a[N]

)

Create a span to a container exposing data() and size().

This correctly deals with constness: the returned Span's element type will be whatever data() returns a pointer to. If either the passed container is const, or its element type is const, the resulting span will have a const element type.

std::span will have a constructor that implements this functionality directly.
