Struct ProstCodec 

pub struct ProstCodec<E, D> { /* private fields */ }

Encodes E and decodes D as individual Protobuf payloads.

The directions may use different message types, as is usual for RPC requests and responses. The adapter holds no message data between calls; callers may reuse both the codec and the outbound buffer across messages.

Implementations

impl<E, D> ProstCodec<E, D>

pub const CONTENT_TYPE: &'static str = "application/grpc"

HTTP content type emitted for Protobuf messages.

pub const fn new() -> ProstCodec<E, D>

Creates a codec for the specified outbound and inbound message types.

pub fn accepts_content_type(content_type: &str) -> bool

Accepts the default gRPC media type and its explicit Protobuf variant.

Media types are compared case-insensitively, ignoring surrounding HTTP whitespace and optional media type parameters.

Trait Implementations

impl<E, D> Codec for ProstCodec<E, D>

where E: Message, D: Message + Default,

const CONTENT_TYPE: &'static str = Self::CONTENT_TYPE

HTTP content type identifying this serialization format.

type EncodeItem = E

Message type accepted by the encoder.

type DecodeItem = D

Owned message type returned by the decoder.

type Error = ProstCodecError

Serialization or deserialization failure.

fn encode( &mut self, item: &E, destination: &mut Vec<u8>, ) -> Result<(), <ProstCodec<E, D> as Codec>::Error>

Appends one serialized message to destination.

fn decode( &mut self, payload: &[u8], ) -> Result<D, <ProstCodec<E, D> as Codec>::Error>

Decodes exactly one message payload.

impl<E, D> Debug for ProstCodec<E, D>

where E: Debug, D: Debug,

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

Formats the value using the given formatter.

impl<E, D> Default for ProstCodec<E, D>

fn default() -> ProstCodec<E, D>

Returns the “default value” for a type.
