Trait Implementations

impl BinaryEncoder<NodeId> for NodeId

fn byte_len(&self) -> usize

Returns the exact byte length of the structure as it would be if encode were called. This may be called prior to writing to ensure the correct amount of space is available.

fn encode<S: Write>(&self, stream: &mut S) -> EncodingResult<usize>

Encodes the instance to the write stream.

fn decode<S: Read>(
    stream: &mut S,
    decoding_limits: &DecodingLimits
) -> EncodingResult<Self>

Decodes an instance from the read stream. The decoding limits are restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.
