A Protocol Buffers message.

Required methods

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

Provided methods

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut,
    Self: Sized, 

Encodes the message to a buffer.

An error will be returned if the buffer does not have sufficient capacity.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut,
    Self: Sized, 

Encodes the message with a length-delimiter to a buffer.

An error will be returned if the buffer does not have sufficient capacity.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes an instance of the message from a buffer.

The entire buffer will be consumed.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf,
    Self: Sized, 

Decodes an instance of the message from a buffer, and merges it into self.

The entire buffer will be consumed.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf,
    Self: Sized, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.
