Public Member Functions
constexpr bool	isValid () const
	Returns true only after the parser completed every validation pass.
constexpr std::string_view	name (NameRef reference) const
	Returns a module-owned identifier spelling.
constexpr std::string_view	source () const
	Returns the validated WGSL source retained for WGSL projection.
constexpr uint32_t	typeAlignment (Type type) const
	Returns natural host-shareable alignment, or zero for an unsupported type.
constexpr uint32_t	typeSize (Type type) const
	Returns fixed byte size; runtime arrays and unsupported types have size zero.
constexpr uint32_t	arrayStride (Type type) const
	Returns the array element stride, including trailing element padding.
