Struct BytesCodec 

pub struct BytesCodec;

只搬字节的 codec —— 让 tonic 在不知道消息类型的前提下完成一次 unary 调用。

Trait Implementations

impl Clone for BytesCodec

fn clone(&self) -> BytesCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for BytesCodec

type Encode = Vec<u8>

The encodable message.

type Decode = Vec<u8>

The decodable message.

type Encoder = BytesCodec

The encoder that can encode a message.

type Decoder = BytesCodec

The decoder that can decode a message.

fn encoder(&mut self) -> Self::Encoder

Fetch the encoder.

fn decoder(&mut self) -> Self::Decoder

impl Copy for BytesCodec

impl Debug for BytesCodec

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

Formats the value using the given formatter.

impl Decoder for BytesCodec

fn decode( &mut self, src: &mut DecodeBuf<'_>, ) -> Result<Option<Self::Item>, Self::Error>

tonic 保证 src 里正好是一条完整消息，不用自己拆帧

type Item = Vec<u8>

The type that is decoded.

type Error = Status

The type of unrecoverable frame decoding errors.

fn buffer_settings(&self) -> BufferSettings

Controls how tonic creates and expands decode buffers.

impl Default for BytesCodec

fn default() -> BytesCodec

Returns the “default value” for a type.

impl Encoder for BytesCodec

type Item = Vec<u8>

The type that is encoded.

type Error = Status

The type of encoding errors.

fn encode( &mut self, item: Self::Item, dst: &mut EncodeBuf<'_>, ) -> Result<(), Self::Error>

Encodes a message into the provided buffer.

fn buffer_settings(&self) -> BufferSettings

Controls how tonic creates and expands encode buffers.
