Struct ServiceInstance 

pub struct ServiceInstance {
    pub service: String,
    pub id: String,
    pub endpoint: InstanceEndpoint,
    pub metadata: BTreeMap<String, String>,
    pub healthy: bool,
    pub weight: u32,
}

A discoverable service instance.

Fields

service: String

Service name used by discovery clients.

id: String

Stable instance id inside a service.

endpoint: InstanceEndpoint

Network endpoint.

metadata: BTreeMap<String, String>

Free-form metadata for adapters and clients.

healthy: bool

Whether this instance is considered healthy.

weight: u32

Relative weight used by selectors.

Implementations

impl ServiceInstance

pub fn new( service: impl Into<String>, id: impl Into<String>, endpoint: InstanceEndpoint, ) -> Self

Creates a healthy service instance with weight 1.

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Adds metadata and returns the updated instance.

pub fn with_health(self, healthy: bool) -> Self

Sets the health flag and returns the updated instance.

pub fn with_weight(self, weight: u32) -> Self

Sets the selector weight. Zero is normalized to one.

Trait Implementations

impl Clone for ServiceInstance

fn clone(&self) -> ServiceInstance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceInstance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServiceInstance

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ServiceInstance

fn eq(&self, other: &ServiceInstance) -> 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 ServiceInstance

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
