Data Structures
union	arch::s390x::cpu::teid::teid
	Union view of a 64-bit TEID. More...

Functions
constexpr auto	address () const noexcept -> u64
	Extract the page-aligned translation-exception address.
constexpr auto	asce_id () const noexcept -> u64
	Extract the ASCE identifier ( bits 62-63).
constexpr auto	fsi_raw () const noexcept -> u64
	Extract the AEFSI fetch/store indication.
constexpr auto	is_fetch () const noexcept -> bool
	True if AEFSI says the access was an instruction fetch.
constexpr auto	is_side_effect () const noexcept -> bool
	True if bit 54 (side-effect-access indication) is set.
constexpr auto	is_store () const noexcept -> bool
	True if AEFSI says the access was a store.
constexpr auto	protection_is_alc () const noexcept -> bool
	True if the protection code reported by basic SOP / ESOP-1 indicates access-list-controlled (ALC) protection.
constexpr auto	protection_is_exec () const noexcept -> bool
	True if the 3-bit protection code (bits 56, 60, 61) decodes to 101.
