Struct NodeId 

pub struct NodeId(pub [u8; 32]);

NodeId is the 32-byte identifier that uniquely names a node in the NWEP network.

A node ID is derived by applying a cryptographic hash to the node’s Ed25519 public key, so it is bound to the key material and cannot be forged without possession of the private key.

Node IDs are displayed as lowercase hex strings (64 characters). The all-zero value is reserved and considered invalid; use NodeId::is_zero to test for it.

Example

use nwep::types::NodeId;

let id = NodeId([0u8; 32]);
assert!(id.is_zero());
println!("{id}"); // 0000...0000

Tuple Fields

0: [u8; 32]

Implementations

impl NodeId

pub fn is_zero(&self) -> bool

is_zero returns true if all bytes of this node ID are zero.

An all-zero node ID is the uninitialized/invalid sentinel value. Use this check to guard against unset node IDs before sending them over the wire.

pub fn as_bytes(&self) -> &[u8; 32]

as_bytes returns a reference to the raw 32-byte node ID array.

Useful when the bytes must be passed to a C API or hashed directly without copying.

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeId

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

Formats the value using the given formatter.

impl Default for NodeId

fn default() -> NodeId

Returns the “default value” for a type.

impl Display for NodeId

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

Formats the value using the given formatter.

impl Hash for NodeId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeId

fn eq(&self, other: &NodeId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
