Struct ProtobufCodec 

pub struct ProtobufCodec;

Implements Codec for the Protocol Buffers binary format.

This codec handles the application/octet-stream content type.

Trait Implementations

impl Clone for ProtobufCodec

fn clone(&self) -> ProtobufCodec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Codec for ProtobufCodec

fn encode<T: Message + Serialize>( &self, val: &T, _mime: Option<&str>, ) -> Result<Bytes, GatewayError>

Encodes a message using prost.

Parameters

• val: The message to encode.
• _mime: Ignored.

Returns

The binary protobuf encoding of the message.

Errors

Returns GatewayError::Encoding if the encoding process fails.

fn decode<T: Message + Default + DeserializeOwned>( &self, buf: &[u8], _mime: Option<&str>, ) -> Result<T, GatewayError>

Decodes a message using prost.

Parameters

• buf: The binary data to decode.
• _mime: Ignored.

Returns

The decoded message object.

Errors

Returns GatewayError::Encoding if the data cannot be decoded into the target type.

fn encoder_content_type(&self, _accept: Option<&str>) -> String

Returns the content type that this codec will use for encoding.

impl Debug for ProtobufCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProtobufCodec

fn default() -> ProtobufCodec

Returns the “default value” for a type.
