Struct qt_core::q_meta_type::TypeFlag

#[repr(transparent)]pub struct TypeFlag(_);

The enum describes attributes of a type supported by QMetaType.

C++ enum: QMetaType::TypeFlag.

C++ documentation:

The enum describes attributes of a type supported by QMetaType.

The TypeFlags type is a typedef for QFlags<TypeFlag>. It stores an OR combination of TypeFlag values.

Methods

impl TypeFlag

pub fn to_int(&self) -> c_int

impl TypeFlag

pub const NeedsConstruction: TypeFlag

This type has non-trivial constructors. If the flag is not set instances can be safely initialized with memset to 0. (C++ enum variant: NeedsConstruction = 1)

pub const NeedsDestruction: TypeFlag

This type has a non-trivial destructor. If the flag is not set calls to the destructor are not necessary before discarding objects. (C++ enum variant: NeedsDestruction = 2)

pub const MovableType: TypeFlag

An instance of a type having this attribute can be safely moved by memcpy. (C++ enum variant: MovableType = 4)

pub const PointerToQObject: TypeFlag

This type is a pointer to a derived of QObject This type is a Q_GADGET and it's corresponding QMetaObject can be accessed with QMetaType::metaObject Since 5.5. (C++ enum variant: PointerToQObject = 8)

pub const IsEnumeration: TypeFlag

This type is an enumeration (C++ enum variant: IsEnumeration = 16)

pub const SharedPointerToQObject: TypeFlag

C++ enum variant: SharedPointerToQObject = 32

pub const WeakPointerToQObject: TypeFlag

C++ enum variant: WeakPointerToQObject = 64

pub const TrackingPointerToQObject: TypeFlag

C++ enum variant: TrackingPointerToQObject = 128

pub const WasDeclaredAsMetaType: TypeFlag

C++ enum variant: WasDeclaredAsMetaType = 256

pub const IsGadget: TypeFlag

C++ enum variant: IsGadget = 512

pub const PointerToGadget: TypeFlag

C++ enum variant: PointerToGadget = 1024
