Provided Methods§
sourcefn has_property(&self, property_name: &str, type_: Option<Type>) -> bool
fn has_property(&self, property_name: &str, type_: Option<Type>) -> bool
Check if the object class has a property property_name
of the given type_
.
If no type is provided then only the existence of the property is checked.
sourcefn property_type(&self, property_name: &str) -> Option<Type>
fn property_type(&self, property_name: &str) -> Option<Type>
Get the type of the property property_name
of this object class.
This returns None
if the property does not exist.
sourcefn find_property(&self, property_name: &str) -> Option<ParamSpec>
fn find_property(&self, property_name: &str) -> Option<ParamSpec>
Get the ParamSpec
of the property property_name
of this object class.
sourcefn list_properties(&self) -> PtrSlice<ParamSpec>
fn list_properties(&self) -> PtrSlice<ParamSpec>
Return all ParamSpec
of the properties of this object class.
