Module serde_protobuf::de

Deserialization of binary protocol buffer encoded data.

All deserialization operations require a previously loaded set of schema descriptors; see the descriptor module for more information.

Provided that a set of descriptors have been loaded, a Deserializer can be used to deserialize a stream of bytes into something that implements Deserialize.

// Load a descriptor registry (see descriptor module)
let mut file = fs::File::open("testdata/descriptors.pb")?;
let proto = protobuf::parse_from_reader(&mut file)?;
let descriptors = Descriptors::from_proto(&proto);

// Set up some data to read
let data = &[8, 42];
let mut input = protobuf::CodedInputStream::from_bytes(data);

// Create a deserializer
let name = ".protobuf_unittest.TestAllTypes";
let mut deserializer = Deserializer::for_named_message(&descriptors, name, input)?;

// Deserialize some struct
let value = Value::deserialize(&mut deserializer)?;
