Trait PyClassDict 

pub trait PyClassDict: Sealed {
    const INIT: Self;

    // Provided methods
    fn clear_dict(&self, _py: Python<'_>) { ... }
    fn release_dict(&mut self, _py: Python<'_>) { ... }
    unsafe fn traverse_dict(
        &self,
        _visit: visitproc,
        _arg: *mut c_void,
    ) -> c_int { ... }
}

Represents the __dict__ field for #[pyclass].

Required Associated Constants

const INIT: Self

Initial form of a PyObject __dict__ reference.

Provided Methods

fn clear_dict(&self, _py: Python<'_>)

Empties the dictionary of its key-value pairs.

fn release_dict(&mut self, _py: Python<'_>)

Releases the owned reference to the dictionary.

unsafe fn traverse_dict(&self, _visit: visitproc, _arg: *mut c_void) -> c_int

Visits the __dict__, if any, on behalf of tp_traverse.

Safety

• Must only be called from a tp_traverse implementation, passing that implementation’s visit and arg unchanged.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
