Expand description
Adds Deserialize
implementation to structs to be deserialized from a{sv}
type.
This macro deserializes a D-Bus dictionary type as a struct, where keys are strings and values are generic values. Such dictionary types are very commonly used with D-Bus and GVariant.
Examples
For structs it works just like serde’s Deserialize
macros:
use zvariant::{DeserializeDict, Type};
#[derive(DeserializeDict, Type)]
#[zvariant(signature = "a{sv}")]
struct Struct {
field1: u16,
#[zvariant(rename = "another-name")]
field2: i64,
optional_field: Option<String>,
}
The deserialized D-Bus dictionary {"field1": Value::U16(42), "another-name": Value::I64(77)}
will be Struct {42, 77, None}
.
