Trait pyo3::PyTryInto

pub trait PyTryInto<T>: Sized {
    type Error;
    fn try_into(&self) -> Result<&T, Self::Error>;
    fn try_into_exact(&self) -> Result<&T, Self::Error>;
    fn try_into_mut(&self) -> Result<&mut T, Self::Error>;
    fn try_into_mut_exact(&self) -> Result<&mut T, Self::Error>;
}

Trait implemented by Python object types that allow a checked downcast. This trait is similar to std::convert::TryInto
