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. Read more

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

Encodes the instance to the write stream.

fn decode<S>(
