clang::mrdocs::dom::HasLazyObjectMapWithoutContext

Concept to determine if a type can be mapped to a dom::LazyObjectImpl with a user-provided conversion.

Synopsis

Declared in <mrdocs/Dom/LazyObject.hpp>
template<class T>
concept HasLazyObjectMapWithoutContext = requires(
    detail::ArchetypalIO& io,
    T const& t)
{
    { tag_invoke(LazyObjectMapTag{}, io, t) } -> std::same_as<void>;
};

Description

This concept determines if the user-provided conversion is defined as:

template void tag_invoke( LazyObjectMapTag, IO&, T& );

This customization can be defined by any type that needs to be converted to/from a lazy dom::Object. For example:

template void tag_invoke( LazyObjectMapTag, IO& io, MyStruct const& s) { io.map("name", s.name); io.map("size", s.size); io.map("age", s.age); }
