Struct protobuf_codec::scalar::CustomBytesDecoder

pub struct CustomBytesDecoder<D>(_);

Decoder for custom bytes values.

This is equivalent to BytesDecoder in the protobol buffers layer, but it decodes the payload bytes by using D and returns the decoded items to the application layer instead of raw bytes.

Methods

impl<D: Decode> CustomBytesDecoder<D>

pub fn new(inner: D) -> Self

Makes a new CustomBytesDecoder instance.

pub fn inner_ref(&self) -> &D

Returns a reference to the inner decoder.

pub fn inner_mut(&mut self) -> &mut D

Returns a mutable reference to the inner decoder.

pub fn into_inner(self) -> D

Takes ownership of the instance and returns the inner decoder.

Trait Implementations

impl<D: Debug> Debug for CustomBytesDecoder<D>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<D: Default> Default for CustomBytesDecoder<D>

fn default() -> CustomBytesDecoder<D>

Returns the "default value" for a type.

impl<D: Decode> Decode for CustomBytesDecoder<D>

type Item = D::Item

The type of items to be decoded.

fn decode(&mut self, buf: &[u8], eos: Eos) -> Result<usize>

Consumes the given buffer (a part of a byte sequence), and proceeds the decoding process.

fn finish_decoding(&mut self) -> Result<Self::Item>

Finishes the current decoding process and returns the decoded item.

fn requiring_bytes(&self) -> ByteCount

Returns the lower bound of the number of bytes needed to decode the next item.

fn is_idle(&self) -> bool

Returns true if there are no items to be decoded by the decoder at the next invocation of decode method, otherwise false.

impl<D: Decode> ValueDecode for CustomBytesDecoder<D>

fn wire_type(&self) -> WireType

Returns the wire type of the value.
