Derive Macro ToWXF 

#[derive(ToWXF)]
{
    // Attributes available to this derive:
    #[wolfram]
}

Derive ToWXF for a struct or enum.

Structs

Named-field structs encode as a WL Association (<|…|>). Field names are converted to camelCase by default:

use wolfram_serialize::{ToWXF, to_wxf};

#[derive(ToWXF)]
struct Point {
    x: f64,   // → "x" key
    y: f64,   // → "y" key
}
// Encodes as <|"x" -> 1.0, "y" -> 2.0|>
let bytes = to_wxf(&Point { x: 1.0, y: 2.0 }, None).unwrap();

Tuple structs encode as a WL List:

use wolfram_serialize::{ToWXF, to_wxf};

#[derive(ToWXF)]
struct Pair(i64, i64);
// Encodes as {1, 2}
let bytes = to_wxf(&Pair(1, 2), None).unwrap();

Enums

Enum variants encode as <|"Enum" -> "VariantName", "Data" -> {fields…}|>. Unit variants omit the "Data" key:

use wolfram_serialize::{ToWXF, to_wxf};

#[derive(ToWXF)]
enum Color {
    Red,
    Rgb(u8, u8, u8),
}
// Red   → <|"Enum" -> "Red"|>
// Rgb   → <|"Enum" -> "Rgb", "Data" -> {255, 0, 0}|>
let _ = to_wxf(&Color::Red, None).unwrap();
let _ = to_wxf(&Color::Rgb(255, 0, 0), None).unwrap();

Special field types

Rust field type	WL wire encoding
Vec<u8>	ByteArray[…]
Vec<f64> / Vec<i64> / …	NumericArray[…, "Real64"] / "Integer64" / …
Vec<T: WxfStruct>	{…} (List of Associations)
Option<T>	<|"Enum" -> "Some"/"None", "Data" -> {v}|>

Field attributes

use wolfram_serialize::ToWXF;

#[derive(ToWXF)]
struct Config {
    #[wolfram(rename = "MaxCount")]
    max_count: i64,
}
// Encodes the field as "MaxCount" instead of "maxCount"
