Trait PyTypeCheck

pub trait PyTypeCheck {
    const NAME: &'static str;
    const PYTHON_TYPE: &'static str;

    // Required method
    fn type_check(object: &Bound<'_, PyAny>) -> bool;
}

Implemented by types which can be used as a concrete Python type inside Py<T> smart pointers.

Required Associated Constants

const NAME: &'static str

Name of self. This is used in error messages, for example.

const PYTHON_TYPE: &'static str

Available on crate feature experimental-inspect only.

Provides the full python type of the allowed values.

Required Methods

fn type_check(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of Self, which may include a subtype.

This should be equivalent to the Python expression isinstance(object, Self).

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.
