[−][src]Struct zvariant::EncodingContext
The encoding context to use with the serialization and deserialization API.
This type is generic over the ByteOrder trait. Moreover, the encoding is dependent on the
position of the encoding in the entire message and hence the need to specify the byte
position of the data being serialized or deserialized. Simply pass 0
if serializing or
deserializing to or from the beginning of message, or the preceeding bytes end on an 8-byte
boundry.
Examples
use byteorder::LE; use zvariant::EncodingContext as Context; use zvariant::{from_slice, to_bytes}; let str_vec = vec!["Hello", "World"]; let ctxt = Context::<LE>::new_dbus(0); let encoded = to_bytes(ctxt, &str_vec).unwrap(); // Let's decode the 2nd element of the array only let ctxt = Context::<LE>::new_dbus(14); let decoded: &str = from_slice(&encoded[14..], ctxt).unwrap(); assert_eq!(decoded, "World");
