Struct scylla::transport::Node

pub struct Node {
    pub host_id: Uuid,
    pub address: NodeAddr,
    pub datacenter: Option<String>,
    pub rack: Option<String>,
    /* private fields */
}

Node represents a cluster node along with it’s data and connections

Note: if a Node changes its broadcast address, then it is not longer represented by the same instance of Node struct, but instead a new instance is created (for implementation reasons).

Fields

host_id: Uuid

address: NodeAddr

datacenter: Option<String>

rack: Option<String>

Implementations

impl Node

pub fn sharder(&self) -> Option<Sharder>

pub fn is_down(&self) -> bool

pub fn is_enabled(&self) -> bool

Returns a boolean which indicates whether this node was is enabled. Only enabled nodes will have connections open. For disabled nodes, no connections will be opened.

Trait Implementations

impl Debug for Node

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

Formats the value using the given formatter.

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

This method tests for self and other values to be equal, and is used by ==.

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

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