Struct WeightedBackendService 

#[non_exhaustive]
pub struct WeightedBackendService {
    pub backend_service: Option<String>,
    pub header_action: Option<HttpHeaderAction>,
    pub weight: Option<u32>,
    /* private fields */
}

Available on crate features region-url-maps or url-maps only.

In contrast to a single BackendService in HttpRouteAction to which all matching traffic is directed to,WeightedBackendService allows traffic to be split across multiple backend services. The volume of traffic for each backend service is proportional to the weight specified in each WeightedBackendService

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

backend_service: Option<String>

The full or partial URL to the default BackendService resource. Before forwarding the request to backendService, the load balancer applies any relevant headerActions specified as part of thisbackendServiceWeight.

header_action: Option<HttpHeaderAction>

Specifies changes to request and response headers that need to take effect for the selected backendService.

headerAction specified here take effect beforeheaderAction in the enclosing HttpRouteRule,PathMatcher and UrlMap.

headerAction is not supported for load balancers that have their loadBalancingScheme set to EXTERNAL.

Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true.

weight: Option<u32>

Specifies the fraction of traffic sent to a backend service, computed asweight / (sum of all weightedBackendService weights in routeAction).

The selection of a backend service is determined only for new traffic. Once a user’s request has been directed to a backend service, subsequent requests are sent to the same backend service as determined by the backend service’s session affinity policy. Don’t configure session affinity if you’re using weighted traffic splitting. If you do, the weighted traffic splitting configuration takes precedence.

The value must be from 0 to 1000.

Implementations

impl WeightedBackendService

pub fn new() -> Self

pub fn set_backend_service<T>(self, v: T) -> Self

where T: Into<String>,

Sets the value of backend_service.

Example

let x = WeightedBackendService::new().set_backend_service("example");

pub fn set_or_clear_backend_service<T>(self, v: Option<T>) -> Self

where T: Into<String>,

Sets or clears the value of backend_service.

Example

let x = WeightedBackendService::new().set_or_clear_backend_service(Some("example"));
let x = WeightedBackendService::new().set_or_clear_backend_service(None::<String>);

pub fn set_header_action<T>(self, v: T) -> Self

where T: Into<HttpHeaderAction>,

Sets the value of header_action.

Example

use google_cloud_compute_v1::model::HttpHeaderAction;
let x = WeightedBackendService::new().set_header_action(HttpHeaderAction::default()/* use setters */);

pub fn set_or_clear_header_action<T>(self, v: Option<T>) -> Self

where T: Into<HttpHeaderAction>,

Sets or clears the value of header_action.

Example

use google_cloud_compute_v1::model::HttpHeaderAction;
let x = WeightedBackendService::new().set_or_clear_header_action(Some(HttpHeaderAction::default()/* use setters */));
let x = WeightedBackendService::new().set_or_clear_header_action(None::<HttpHeaderAction>);

pub fn set_weight<T>(self, v: T) -> Self

where T: Into<u32>,

Sets the value of weight.

Example

let x = WeightedBackendService::new().set_weight(42_u32);

pub fn set_or_clear_weight<T>(self, v: Option<T>) -> Self

where T: Into<u32>,

Sets or clears the value of weight.

Example

let x = WeightedBackendService::new().set_or_clear_weight(Some(42_u32));
let x = WeightedBackendService::new().set_or_clear_weight(None::<u32>);

Trait Implementations

impl Clone for WeightedBackendService

fn clone(&self) -> WeightedBackendService

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WeightedBackendService

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

Formats the value using the given formatter.

impl Default for WeightedBackendService

fn default() -> WeightedBackendService

Returns the “default value” for a type.

impl Message for WeightedBackendService

fn typename() -> &'static str

The typename of this message.

impl PartialEq for WeightedBackendService

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