A Protocol Buffers message.
Required Methods§
Sourcefn encoded_len(&self) -> usize
fn encoded_len(&self) -> usize
Returns the encoded length of the message without a length delimiter.
Provided Methods§
Sourcefn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>
fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>
Encodes the message to a buffer.
An error will be returned if the buffer does not have sufficient capacity.
Sourcefn encode_to_vec(&self) -> Vec<u8> ⓘwhere
Self: Sized,
fn encode_to_vec(&self) -> Vec<u8> ⓘwhere
Self: Sized,
Encodes the message to a newly allocated buffer.
Sourcefn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>
fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>
Encodes the message with a length-delimiter to a buffer.
An error will be returned if the buffer does not have sufficient capacity.
Sourcefn encode_length_delimited_to_vec(&self) -> Vec<u8> ⓘwhere
Self: Sized,
fn encode_length_delimited_to_vec(&self) -> Vec<u8> ⓘwhere
Self: Sized,
Encodes the message with a length-delimiter to a newly allocated buffer.
Sourcefn decode<B>(buf: B) -> Result<Self, DecodeError>
fn decode<B>(buf: B) -> Result<Self, DecodeError>
Decodes an instance of the message from a buffer.
The entire buffer will be consumed.
Sourcefn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>
fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>
Decodes a length-delimited instance of the message from the buffer.
Sourcefn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>
fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>
Decodes an instance of the message from a buffer, and merges it into self.
The entire buffer will be consumed.
Sourcefn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>
fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>
Decodes a length-delimited instance of the message from buffer, and
merges it into self.
