[−][src]Derive Macro zvariant::derive::DeserializeDict
#[derive(DeserializeDict)] { // Attributes available to this derive: #[zvariant] }
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::{EncodingContext, to_bytes}; use zvariant_derive::{DeserializeDict, TypeDict}; #[derive(DeserializeDict, TypeDict)] 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}
.
