Detailed Description

template<typename T0, typename T1, typename SFINAE = void>
struct serac::detail::variant_storage< T0, T1, SFINAE >

Storage abstraction to provide trivial destructor when both variant types are trivially destructible.

Template Parameters

T0	The type of the first variant element
T1	The type of the second variant element
SFINAE	Used to switch between the trivially destructible and not-trivially destructible implementations

Member Function Documentation

clear()

template<typename T0 , typename T1 , typename SFINAE = void>

constexpr void serac::detail::variant_storage< T0, T1, SFINAE >::clear ( )

inlineconstexpr
