Struct NodeHash 

pub struct NodeHash { /* private fields */ }

Hash-based node identifier for efficient lookup.

NodeHash uses FNV-1a hashing to convert node IDs into fixed-size hash values for efficient cache lookups. It also supports a wildcard value for broadcast scenarios.

Example

use xds_core::NodeHash;

let node1 = NodeHash::from_id("envoy-node-1");
let node2 = NodeHash::from_id("envoy-node-2");
let wildcard = NodeHash::wildcard();

assert_ne!(node1, node2);
assert!(wildcard.is_wildcard());

Implementations

impl NodeHash

pub fn from_id(node_id: &str) -> Self

Create a node hash from a node ID string.

Uses FNV-1a hashing for fast, well-distributed hashes.

pub fn wildcard() -> Self

Create a wildcard node hash that matches all nodes.

This is used when you want to set a snapshot that applies to all nodes that don’t have a specific snapshot.

pub fn is_wildcard(&self) -> bool

Check if this is a wildcard hash.

pub fn as_u64(&self) -> u64

Get the raw hash value.

Trait Implementations

impl Clone for NodeHash

fn clone(&self) -> NodeHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeHash

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

Formats the value using the given formatter.

impl Default for NodeHash

fn default() -> Self

Returns the “default value” for a type.

impl Display for NodeHash

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

Formats the value using the given formatter.

impl Hash for NodeHash

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 NodeHash

fn eq(&self, other: &NodeHash) -> 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.
