pub struct CFPropertyList(_);
Expand description

A CFPropertyList struct. This is superclass to CFData, CFString, CFArray, CFDictionary, CFDate, CFBoolean, and CFNumber.

This superclass type does not have its own CFTypeID, instead each instance has the CFTypeID of the subclass it is an instance of. Thus, this type cannot implement the TCFType trait, since it cannot implement the static TCFType::type_id() method.

Implementations

Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero.

Returns the type ID of this object. Will be one of CFData, CFString, CFArray, CFDictionary, CFDate, CFBoolean, or CFNumber.

Writes a debugging version of this object on standard error.

Returns true if this value is an instance of another type.

Try to downcast the CFPropertyList to a subclass. Checking if the instance is the correct subclass happens at runtime and None is returned if it is not the correct type. Works similar to Box::downcast and CFType::downcast.

Examples
// Create a string.
let string: CFString = CFString::from_static_string("FooBar");
// Cast it up to a property list.
let propertylist: CFPropertyList = string.to_CFPropertyList();
// Cast it down again.
assert!(propertylist.downcast::<CFString>().unwrap().to_string() == "FooBar");

Similar to downcast, but consumes self and can thus avoid touching the retain count.
