Trait to separate Enums
A trait that helps split up an vector of enums into a tuple with a vector per variant. Please let me know if such a functionality can be achieved in Rust without the macro.
use separable::Separable;
#[derive(Separable)]
enum Temperature {
Celsius(f64),
Fahrenheit(f64),
Kelvin(f64)
}
fn main() {
// A bunch of measurements...
let measurements = vec![
Temperature::Celsius(23.0),
Temperature::Fahrenheit(2.0),
Temperature::Celsius(22.5),
Temperature::Kelvin(288.0),
Temperature::Celsius(23.1),
Temperature::Fahrenheit(5.0)
];
// We separate all the variants, in order
let (celsius, fahrenheit, kelvin) = measurements.into_iter().collect();
// Quick verification
assert_eq!(celsius, vec![23.0f64, 22.5f64, 23.1f64]);
assert_eq!(fahrenheit, vec![2.0f64, 5.0f64]);
assert_eq!(kelvin, vec![288.0f64]);
}
