Public Member Functions
template<AnyFlag F> requires AllowedFlag<F, Categories...>
Derived &	insert_flag ()
	Insert flag F (no-op if already present).
template<AnyFlag F> requires AllowedFlag<F, Categories...>
Derived &	flag ()
	Alias for insert_flag that reads naturally in a fluent chain (builder.flag<F>()).
template<AnyFlag F> requires AllowedFlag<F, Categories...>
Derived &	set_flag (const bool on)
	Set flag F's presence: insert when on, erase otherwise.
Derived &	set_flags (FlagSet flags)
	Replace the whole set.

Static Public Attributes
template<AnyFlag F>
static constexpr bool	flag_allowed = AllowedFlag<F, Categories...>
	True when a flag in F's category is permitted by this builder's constraint.

Protected Member Functions
const FlagSet &	flags () const noexcept
	Read access kept protected and used internally; FlagBuilderGetters publishes it through IHasFlags.

Detailed Description

template<typename Derived, typename... Categories>
class comms::FlagBuilderMixin< Derived, Categories >

CRTP helper for builders.

Owns its own FlagSet and adds fluent mutators that return Derived& for chaining.

It does not expose the set publicly or implement IHasFlags: flags() is protected, used internally. A builder that should keep its flags to itself inherits this directly; one that should be observable inherits FlagBuilderGetters instead.

The typed overloads are constrained to allowed categories; the runtime FlagRef/name overloads are unconstrained (the category is only known at compile time), so prefer the typed ones to keep the constraint.
