Detailed Description

Type-erased, two-word handle to an unwind hint registry.

Constructor & Destructor Documentation

◆ unwind_hint_registry_ref() [1/3]

constexpr microfmt::unwind_hint_registry_ref::unwind_hint_registry_ref ( )

constexprdefaultnoexcept

Constructs an empty (invalid) handle.

◆ unwind_hint_registry_ref() [2/3]

template<typename Tag , typename Context , typename Traits = unwind_hint_registry_traits<Tag>, std::enable_if_t< std::is_convertible_v< const Context *, const typename Traits::context_type * >, int > = 0>

constexpr microfmt::unwind_hint_registry_ref::unwind_hint_registry_ref	(	Tag	,
		const Context &ctx RELOCO_LIFETIMEBOUND	RELOCO_LIFETIME_CAPTURE_BY_THIS
	)

inlineconstexprnoexcept

Constructs a handle for a stateful registry tag.

Template Parameters

Tag	Registry tag type.
Context	Concrete context convertible to the trait context type.

Parameters

ctx	Context object performing the lookup.

◆ unwind_hint_registry_ref() [3/3]

template<typename Tag , typename Context , std::enable_if_t<!std::is_lvalue_reference_v< Context >, int > = 0>

Member Function Documentation

◆ find_hint()

bool microfmt::unwind_hint_registry_ref::find_hint	(	uintptr_t	pc,
		unwind_hint &	out_hint
	)		const

inlinenoexcept

Looks up the hint covering a PC.

Parameters

pc	PC being looked up.
out_hint	Receives the matching hint.

Returns: true when a hint matched.

◆ make() [1/2]

template<typename Tag , typename Context , typename Traits = unwind_hint_registry_traits<Tag>>

static constexpr unwind_hint_registry_ref microfmt::unwind_hint_registry_ref::make ( const Context &ctx RELOCO_LIFETIMEBOUND )

inlinestaticconstexprnoexcept

◆ make() [2/2]

template<typename Tag , typename Context , std::enable_if_t<!std::is_lvalue_reference_v< Context >, int > = 0>

static unwind_hint_registry_ref microfmt::unwind_hint_registry_ref::make ( Context && )

staticdelete

◆ operator bool()

constexpr microfmt::unwind_hint_registry_ref::operator bool ( ) const

inlineexplicitconstexprnoexcept

Reports whether the handle is bound to a registry.

Returns: true when the handle is valid.
