Struct Node 

pub struct Node {
    pub id: String,
    pub ip: IpAddr,
    pub last_seen: i64,
    pub metadata: NodeMetadata,
}

Represents a node in the cluster.

Each node has a unique identifier, network address, and timestamp of when it was last seen by the cluster.

Equality

Two nodes are considered equal if they have the same id and ip. The last_seen timestamp and metadata are intentionally excluded from equality checks to allow detecting actual state changes vs heartbeat updates.

Metadata

The optional metadata field allows nodes to report arbitrary data (CPU load, memory, custom metrics) that can be used by load balancers for weighted routing decisions.

Fields

id: String

Unique identifier for this node

ip: IpAddr

Network address of this node

last_seen: i64

Unix timestamp (milliseconds) when this node was last seen

metadata: NodeMetadata

Optional node metadata (CPU, memory, custom metrics) Defaults to null if not provided (backward compatible)

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Node

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Node

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Node

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 Node

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

impl Serialize for Node

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
