Get the original datatype values from a vector of AnyValues

I can convert many datatypes into the AnyValue enum in Rust Polars. but how do I convert them back to the original datatypes?

use polars::prelude::*;

fn main() {
    let df = df!(  "Fruit" => &["Apple", "Apple", "Pear"],
                   "Boolean" => &[true,false,true],
                   "Float64" => &[1.1,321.45,101.445])
    .unwrap();

    // get row 1 of the DataFrame as a vector of AnyValues
    let vec_anyvalue = df.get(1).unwrap();

    // trying to get the actual values:

    // getting the fruit as a String kind of works (get quotation marks too)
    let fruit = vec_anyvalue.get(0).unwrap().to_string();

    // getting the bool or the float value does not ?!

    // ERROR:  the trait `From<&AnyValue<'_>>` is not implemented for `bool`
    let boolvalue: bool = vec_anyvalue.get(1).unwrap().into();
    // ERROR:  the trait `From<AnyValue<'_>>` is not implemented for `f64`
    let floatvalue: f64 = vec_anyvalue.get(2).unwrap().into();
}

I think you have to write a converter yourself:

fn to_bool<'a>(v: &AnyValue<'a>) -> bool {
    if let AnyValue::Boolean(b) = v {
        *b
    } else {
        panic!("not a boolean");
    }
}

(or a variation returning Option/Result)
