Struct protobuf_codec::field::MapFieldEncoder

pub struct MapFieldEncoder<F, K, V, M: IntoIterator> { /* fields omitted */ }

Encoder for map fields which have scalar values.

Methods

impl<F, K, V, M> MapFieldEncoder<F, K, V, M> where
    F: Copy + Into<FieldNum>,
    K: SizedEncode + MapKeyEncode,
    V: SizedEncode + ValueEncode,
    M: IntoIterator<Item = (K::Item, V::Item)>, 

pub fn new(field_num: F, key_encoder: K, value_encoder: V) -> Self

Makes a new MapFieldEncoder instance.

Trait Implementations

impl<F: Default, K: Default, V: Default, M: Default + IntoIterator> Default for MapFieldEncoder<F, K, V, M>

fn default() -> MapFieldEncoder<F, K, V, M>

Returns the "default value" for a type.

impl<F, K, V, M> Encode for MapFieldEncoder<F, K, V, M> where
    F: Copy + Into<FieldNum>,
    K: SizedEncode + MapKeyEncode,
    V: SizedEncode + ValueEncode,
    M: IntoIterator<Item = (K::Item, V::Item)>, 

type Item = M

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.

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

Formats the value using the given formatter.
