Trait QMetaTypeCompatible 

pub trait QMetaTypeCompatible {
    type CompatibleType: QMetaTypeGet;

    // Required methods
    fn to_compatible(&self) -> Self::CompatibleType;
    fn from_compatible(from: &Self::CompatibleType) -> Self;

    // Provided method
    fn compatible_qmetatype() -> QMetaType { ... }
}

Enables a type to be used as a meta call argument and to be convertible from/to QVariant.

Implemented for:

• Primitive numeric types and bool
• String
• Vec<T> where T is one of the above
• Rc<RefCell<T>> where T implements [QObjectHolder]
• Vec<Rc<RefCell<T>>> where T implements QmlElement

Required Associated Types

type CompatibleType: QMetaTypeGet

Required Methods

fn to_compatible(&self) -> Self::CompatibleType

fn from_compatible(from: &Self::CompatibleType) -> Self

Provided Methods

fn compatible_qmetatype() -> QMetaType

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
