Struct aws_sdk_evidently::client::fluent_builders::EvaluateFeature

pub struct EvaluateFeature { /* private fields */ }

Fluent builder constructing a request to EvaluateFeature.

This operation assigns a feature variation to one given user session. You pass in an entityID that represents the user. Evidently then checks the evaluation rules and assigns the variation.

The first rules that are evaluated are the override rules. If the user's entityID matches an override rule, the user is served the variation specified by that rule.

Next, if there is a launch of the feature, the user might be assigned to a variation in the launch. The chance of this depends on the percentage of users that are allocated to that launch. If the user is enrolled in the launch, the variation they are served depends on the allocation of the various feature variations used for the launch.

If the user is not assigned to a launch, and there is an ongoing experiment for this feature, the user might be assigned to a variation in the experiment. The chance of this depends on the percentage of users that are allocated to that experiment. If the user is enrolled in the experiment, the variation they are served depends on the allocation of the various feature variations used for the experiment.

If the user is not assigned to a launch or experiment, they are served the default variation.

Implementations

impl EvaluateFeature

pub async fn send(
    self
) -> Result<EvaluateFeatureOutput, SdkError<EvaluateFeatureError>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn project(self, input: impl Into<String>) -> Self

The name or ARN of the project that contains this feature.

pub fn set_project(self, input: Option<String>) -> Self

The name or ARN of the project that contains this feature.

pub fn feature(self, input: impl Into<String>) -> Self

The name of the feature being evaluated.

pub fn set_feature(self, input: Option<String>) -> Self

The name of the feature being evaluated.

pub fn entity_id(self, input: impl Into<String>) -> Self

An internal ID that represents a unique user of the application. This entityID is checked against any override rules assigned for this feature.

pub fn set_entity_id(self, input: Option<String>) -> Self

An internal ID that represents a unique user of the application. This entityID is checked against any override rules assigned for this feature.

pub fn evaluation_context(self, input: impl Into<String>) -> Self

A JSON block of attributes that you can optionally pass in. This JSON block is included in the evaluation events sent to Evidently from the user session.

pub fn set_evaluation_context(self, input: Option<String>) -> Self

A JSON block of attributes that you can optionally pass in. This JSON block is included in the evaluation events sent to Evidently from the user session.
