Enum NodeTarget 

pub enum NodeTarget {
    Default,
    Single(String),
    Multiple(Vec<String>),
}

Represents a target node or set of nodes for API operations

Variants

Default

No specific target - use the connected endpoint

Single(String)

Target a single node by IP or hostname

Multiple(Vec<String>)

Target multiple nodes (for cluster-wide operations)

Implementations

impl NodeTarget

pub fn none() -> Self

Create a target for the default (connected) node

pub fn single(node: impl Into<String>) -> Self

Create a target for a single node

pub fn multiple(nodes: impl IntoIterator<Item = impl Into<String>>) -> Self

Create a target for multiple nodes

pub fn from_csv(csv: &str) -> Self

Create from a comma-separated string

pub fn is_default(&self) -> bool

Check if this is the default target

pub fn is_single(&self) -> bool

Check if this targets a single node

pub fn is_multiple(&self) -> bool

Check if this targets multiple nodes

pub fn nodes(&self) -> &[String]

Get the nodes as a slice (empty for Default)

pub fn first(&self) -> Option<&str>

Get the first node, if any

pub fn to_csv(&self) -> Option<String>

Convert to comma-separated string for gRPC metadata

pub fn apply_to_request<T>(&self, request: Request<T>) -> Request<T>

Apply node targeting to a gRPC request

Trait Implementations

impl Clone for NodeTarget

fn clone(&self) -> NodeTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeTarget

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

Formats the value using the given formatter.

impl Default for NodeTarget

fn default() -> NodeTarget

Returns the “default value” for a type.

impl From<&str> for NodeTarget

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Option<String>> for NodeTarget

fn from(opt: Option<String>) -> Self

Converts to this type from the input type.

impl From<String> for NodeTarget

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Vec<String>> for NodeTarget

fn from(nodes: Vec<String>) -> Self

Converts to this type from the input type.

impl PartialEq for NodeTarget

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