Detailed Description

template<typename T, typename U>
struct swoc::detail::is_span_compatible< T, U >

Meta Function to check the type compatibility of two spans..

Template Parameters

T	Source span type.
U	Destination span type.

The types are compatible if one is an integral multiple of the other, so the span divides evenly.

U must not lose constancy compared to T.

Member Function Documentation

template<typename T, typename U>

size_t swoc::detail::is_span_compatible< T, U >::count ( size_t size )

static

Compute the new size in units of sizeof(U).

Parameters

size	Size in bytes.

The critical part of this is the static_assert that guarantees the result is an integral number of instances of U.

template<typename T, typename U>

staticconstexpr

Initial value:

= (std::ratio<sizeof(T), sizeof(U)>::num == 1 || std::ratio<sizeof(U), sizeof(T)>::num == 1) &&

(std::is_const_v<U> || !std::is_const_v<T>)

true if the size of T is an integral multiple of the size of U or vice versa.
