Working with vectors

[leaden yoke]

My rust function in the backend retuns a vector that contains custom data (data: Vec<Data> for example). How do I work with this vector in the frontend using js?

Provided that Serde can serialize the Data type, it will appear as an array in JS. The following examples are identical declarations.
Rust:

struct Data {
  field_one: String,
  field_two: bool,
}
let data = Data {
  field_one: String::from("Hello, World!"),
  field_two: true,
};

JS:

let data = {
  fieldOne: "Hello, World!",
  fieldTwo: true,
};

So as an array in JS, that can be accessed with:

let data = await invoke("feed_data");
let dataStart = data[0].fieldOne;
