Public Member Functions
	Id ()=delete
	Default-construct the underlying Repr when it is itself default-initializable; otherwise the constructor is deleted (the constrained-defaulted pattern keeps Id usable in containers that require value-initialization).
template<class U > requires std::constructible_from<Repr, U&&> && (!std::is_same_v<std::remove_cvref_t<U>, Id>)
	Id (U &&u)
	Forward into the underlying Repr.
	Id (std::string_view sv)
	Convenience for StringId<Tag>: build directly from a string_view.

Detailed Description

template<class Tag, AllowedIdRepr Repr>
class comms::Id< Tag, Repr >

Strong-typed identifier: a Repr value tagged with a phantom Tag.

Two Ids with different tags are unrelated types even when the underlying representation is identical.

comms::Id< Tag, Repr >::Id ( U &&  u )

inlineexplicit

Forward into the underlying Repr.

Explicit so that an Id is never silently constructed from a raw value.
