Crate zvariant_derive

zvariant_derive

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::{serialized::Context, to_bytes, Type, LE};
use serde::{Deserialize, Serialize};

#[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 = Context::new_dbus(LE, 0);
let encoded = to_bytes(ctxt, &s).unwrap();
let decoded: Struct = encoded.deserialize().unwrap().0;
assert_eq!(decoded, s);

Derive Macros

• DeserializeDict
  Adds Deserialize implementation to structs to be deserialized from a{sv} type.
• OwnedValue
  Implements conversions for your type to/from OwnedValue.
• SerializeDict
  Adds Serialize implementation to structs to be serialized as a{sv} type.
• Type
  Derive macro to add Type implementation to structs and enums.
• Value
  Implements conversions for your type to/from Value.
