Required methods

fn from_tagged_data(src: TaggedData) -> Result<Self, ProtobufError>

Convert from tagged data.

fn to_tagged_data_version(
    &self,
    version: NonZeroU32
) -> Result<TaggedData, ProtobufError>

Convert to tagged data using a specific version.

Errors

  • Returns error if version is unsupported.
  • Returns error if version is supported but is too old to represent this object.

Provided methods

fn to_tagged_data(&self) -> TaggedData

Convert to tagged data using the latest supported version.

The default implementation calls to_tagged_data_version with LATEST_VERSION as version number.

fn from_tagged_data_bytes(bytes: &[u8]) -> Result<Self>

Deserialize from a slice of tagged data bytes.

fn to_tagged_data_bytes(&self) -> Vec<u8>

Serialize to a vector of tagged data bytes.

fn read_from_tagged_data_file<P: AsRef<Path>>(path: P) -> Result<Self>

Read from tagged data file.

fn write_to_tagged_data_file<P: AsRef<Path>>(&self, path: P) -> Result<()>

Write to tagged data file.
