Serializing an euclid::Vec3D with serde

[01010110100010]

I want to serialize an euclid::Vec3D object into a json string using serde. I have this code:

use euclid::{Vector3D, UnknownUnit};
use serde::{Serialize, Deserialize};
use serde_json;

fn main() {
	let v: Vector3D<f64,UnknownUnit> = Vector3D::new(0.,1.,5.);
	let json_str = serde_json::to_string(&v).expect("Failed to serialize");
	dbg!(json_str);
}

which gives me

error[E0277]: the trait bound `Vector3D<f64, UnknownUnit>: Serialize` is not satisfied
    --> src/main.rs:7:39

I understand that the meaning of this is that the serialization method for the euclid::Vec3D objects is not implemented. From what I see, it may be possible to fix this modifying the source code of euclid by adding #[derive(Serialize, Deserialize)] just above the definition of euclid::Vec3D, however I want to keep using the standard version of euclid. How should this be done in my own codebase? My apologies if this is somehow obvious, I am relatively new to Rust.

Source – you want to enable the "serde" feature (and consider reading the documentation…)

And if euclid didn't have a serde feature, what you'd do is instruct serde to (de)serialize your field differently, using #[serde(with = ...)].

Thanks! For quick reference if someone else ends up here, this is done like this in the cargo.toml file:

[dependencies]
euclid = {version = "0.22", features = ["serde"]}

@01010110100010

this is done like this in the cargo.toml file:

And Cargo can do it for you:

cargo add euclid --features serde
