Deserializing TOML into vector of enum with values

Question

I\'m trying to read a TOML file to create a struct that contains a vector of enums with associated values. Here\'s the sample code:

extern crate serde;
#[mac

Serde has lots of options for serializing enums. One that works for your case:

use serde::{Deserialize, Serialize}; // 1.0.117
use toml; // 0.5.7

#[derive(Debug, Serialize, Deserialize, PartialEq)]
#[serde(tag = "type", content = "args")]
enum Actions {
    Wait(usize),
    Move { x: usize, y: usize },
}

fn main() {
    let a_wait = Actions::Wait(5);
    println!("{}", toml::to_string(&a_wait).unwrap());

    let a_move = Actions::Move { x: 1, y: 1 };
    println!("{}", toml::to_string(&a_move).unwrap());
}

type = "Wait"
args = 5

type = "Move"

[args]
x = 1
y = 1
