Struct protobuf_codec::field::MessageFieldEncoder

pub struct MessageFieldEncoder<F, E> { /* fields omitted */ }

Encoder for required embedded message fields.

Methods

impl<F, E> MessageFieldEncoder<F, E> where
    E: MessageEncode + SizedEncode, 

pub fn new(field_num: F, message_encoder: E) -> Self

Makes a new MessageFieldEncoder instance.

Trait Implementations

impl<F: Debug, E: Debug> Debug for MessageFieldEncoder<F, E>

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

Formats the value using the given formatter.

impl<F: Default, E: Default> Default for MessageFieldEncoder<F, E>

fn default() -> MessageFieldEncoder<F, E>

Returns the "default value" for a type.

impl<F, E> Encode for MessageFieldEncoder<F, E> where
    F: Copy + Into<FieldNum>,
    E: MessageEncode + SizedEncode, 

type Item = E::Item

The type of items to be encoded.

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

Encodes the items in the encoder and writes the encoded bytes to the given buffer.

fn start_encoding(&mut self, item: Self::Item) -> Result<()>

Tries to start encoding the given item.

fn is_idle(&self) -> bool

Returns true if there are no items to be encoded in the encoder, otherwise false.

fn requiring_bytes(&self) -> ByteCount

Returns the number of bytes required to encode all the items in the encoder.

impl<F, E> SizedEncode for MessageFieldEncoder<F, E> where
    F: Copy + Into<FieldNum>,
