Trait Implementations

impl Debug for VarintEncoder

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

Formats the value using the given formatter.

impl Default for VarintEncoder

fn default() -> VarintEncoder

Returns the "default value" for a type.

impl Encode for VarintEncoder

type Item = u64

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, n: 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 ExactBytesEncode for VarintEncoder

fn exact_requiring_bytes(&self) -> u64

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