Struct NodeId

#[repr(C)]
pub struct NodeId {
    pub high: u64,
    pub low: u64,
}

A 128-bit node identifier generated from XorShiftRng.

NodeIds uniquely identify clients and nodes in the network. They are formatted as UUID-style strings for human readability and protocol compatibility.

Fields

high: u64

low: u64

Implementations

impl NodeId

pub fn generate(rng: &mut XorShiftRng) -> Self

Generate a new random NodeId using XorShiftRng.

Example

use bbx_core::random::XorShiftRng;
use bbx_net::address::NodeId;

let mut rng = XorShiftRng::new(12345);
let node_id = NodeId::generate(&mut rng);

pub fn generate_with_entropy(clock_micros: u64) -> Self

Generate a NodeId with mixed entropy sources for improved unpredictability.

Combines multiple entropy sources: time, process ID, memory address (ASLR), and a monotonic counter to create a more unpredictable seed.

pub fn generate_unique<F>(clock_micros: u64, exists: F) -> Self

where F: FnMut(&NodeId) -> bool,

Generate a unique NodeId that doesn’t collide with existing IDs.

Uses generate_with_entropy internally and loops until finding an ID that the exists predicate returns false for.

pub const fn from_parts(high: u64, low: u64) -> Self

Create a NodeId from explicit high and low parts.

pub fn to_uuid_string(&self) -> String

Format as hyphenated UUID string.

Returns a string in the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

pub fn from_uuid_string(s: &str) -> Result<Self>

Parse from UUID string.

Accepts the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

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 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.
