// Wrappers for primitive (non-message) types. These types were needed
// for legacy reasons and are not recommended for use in new APIs.
//
// Historically these wrappers were useful to have presence on proto3 primitive
// fields, but proto3 syntax has been updated to support the `optional` keyword.
// Using that keyword is now the strongly preferred way to add presence to
// proto3 primitive fields.
//
// A secondary usecase was to embed primitives in the `google.protobuf.Any`
// type: it is now recommended that you embed your value in your own wrapper
// message which can be specifically documented.
//
// These wrappers have no meaningful use within repeated fields as they lack
// the ability to detect presence on individual elements.
// These wrappers have no meaningful use within a map or a oneof since
// individual entries of a map or fields of a oneof can already detect presence.
