zvariant_derive 3.8.0

D-Bus & GVariant encoding & decoding


This crate provides derive macros helpers for zvariant. The zvariant crate re-exports these macros for your convenience so you do not need to use this crate directly.

Status: Stable.

Example code

use zvariant::{EncodingContext, from_slice, to_bytes, Type};
use serde::{Deserialize, Serialize};
use byteorder::LE;

#[derive(Deserialize, Serialize, Type, PartialEq, Debug)]
struct Struct<'s> {
    field1: u16,
    field2: i64,
    field3: &'s str,

assert_eq!(Struct::signature(), "(qxs)");
let s = Struct {
    field1: 42,
    field2: i64::max_value(),
    field3: "hello",
let ctxt = EncodingContext::<LE>::new_dbus(0);
let encoded = to_bytes(ctxt, &s).unwrap();
let decoded: Struct = from_slice(&encoded, ctxt).unwrap();
assert_eq!(decoded, s);
