Implementations§
Source§impl AXValue
impl AXValue
Sourcepub unsafe fn new(
the_type: AXValueType,
value_ptr: NonNull<c_void>,
) -> Option<CFRetained<AXValue>>
pub unsafe fn new( the_type: AXValueType, value_ptr: NonNull<c_void>, ) -> Option<CFRetained<AXValue>>
Encodes a structure pointed to by valuePtr into a CFTypeRef.
Parameter theType:
Parameter valuePtr:
Returns:
§Safety
value_ptr must be a valid pointer.
Sourcepub unsafe fn type(&self) -> AXValueType
pub unsafe fn type(&self) -> AXValueType
Returns the structure type encoded in value. If the type is not recognized, it returns kAXValueIllegalType.
Parameter value:
Returns:
Sourcepub unsafe fn value(
&self,
the_type: AXValueType,
value_ptr: NonNull<c_void>,
) -> bool
pub unsafe fn value( &self, the_type: AXValueType, value_ptr: NonNull<c_void>, ) -> bool
Decodes the structure stored in value and copies it into valuePtr. If the structure stored in value is not the same as requested by theType, the function returns false.
Parameter value:
Returns:
§Safety
value_ptr must be a valid pointer.
Methods from Deref<Target = CFType>§
Sourcepub fn downcast_ref<T>(&self) -> Option<&T>where
T: ConcreteType,
pub fn downcast_ref<T>(&self) -> Option<&T>where
T: ConcreteType,
Attempt to downcast the type to that of type T.
This is the reference-variant. Use CFRetained::downcast if you
want to convert a retained type. See also ConcreteType for more
details on which types support being converted to.
Sourcepub fn retain_count(&self) -> usize
pub fn retain_count(&self) -> usize
Get the reference count of the object.
This function may be useful for debugging. You normally do not use this function otherwise.
Beware that some things (like CFNumbers, small CFStrings etc.) may
not have a normal retain count for optimization purposes, and can
return usize::MAX in that case.
