Struct qt_core::q_meta_type::TypeFlag

pub struct TypeFlag(/* private fields */);

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.

Implementations

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

Trait Implementations

impl<T: Into<QFlags<TypeFlag>>> BitOr<T> for TypeFlag

type Output = QFlags<TypeFlag>

The resulting type after applying the | operator.

fn bitor(self, rhs: T) -> QFlags<TypeFlag>

Performs the | operation.

impl Clone for TypeFlag

fn clone(&self) -> TypeFlag

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeFlag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<TypeFlag> for QFlags<TypeFlag>

fn from(value: TypeFlag) -> Self

Converts to this type from the input type.

impl From<TypeFlag> for c_int

fn from(value: TypeFlag) -> Self

Converts to this type from the input type.

impl From<i32> for TypeFlag

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for TypeFlag

fn eq(&self, other: &TypeFlag) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
