    T: 'static + Into<Identifier>,

pub fn is_null(&self) -> bool

Test if the node id is null, i.e. 0 namespace and 0 identifier

pub fn null() -> NodeId

Returns a null node id

pub fn next_numeric() -> NodeId

pub fn as_object_id(&self) -> Result<ObjectId, ()>

Extracts an ObjectId from a node id, providing the node id holds an object id

Test if the node id is numeric

pub fn is_string(&self) -> bool

Test if the node id is a string

pub fn is_byte_string(&self) -> bool

Test if the node id us a byte string

Trait Implementations

impl BinaryEncoder<NodeId> for NodeId

fn byte_len(&self) -> usize

Returns the byte length of the structure. This calculation should be exact and as efficient as possible.

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

Encodes the instance to the write stream.

fn decode<S>(
    stream: &mut S,
    decoding_limits: &DecodingLimits
) -> Result<NodeId, StatusCode>where
    S: Read,

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.

fn to_vec(&self) -> Vec<u8, Global>
