Struct VariantManager 

pub struct VariantManager { /* private fields */ }

Manages A/B test configurations and variants

Implementations

impl VariantManager

pub fn new() -> Self

Create a new variant manager

pub async fn register_test(&self, config: ABTestConfig) -> Result<()>

Register an A/B test configuration

pub async fn get_test(&self, method: &str, path: &str) -> Option<ABTestConfig>

Get A/B test configuration for an endpoint

pub async fn list_tests(&self) -> Vec<ABTestConfig>

List all registered A/B tests

pub async fn remove_test(&self, method: &str, path: &str) -> Result<()>

Remove an A/B test configuration

pub async fn get_variant( &self, method: &str, path: &str, variant_id: &str, ) -> Option<MockVariant>

Get a variant by ID for an endpoint

pub async fn record_request( &self, method: &str, path: &str, variant_id: &str, status_code: u16, response_time_ms: f64, )

Record analytics for a variant request

pub async fn get_variant_analytics( &self, method: &str, path: &str, variant_id: &str, ) -> Option<VariantAnalytics>

Get analytics for a variant

pub async fn get_endpoint_analytics( &self, method: &str, path: &str, ) -> HashMap<String, VariantAnalytics>

Get all analytics for an endpoint

pub async fn get_round_robin_index(&self, method: &str, path: &str) -> usize

Get round-robin counter for an endpoint

pub async fn increment_round_robin( &self, method: &str, path: &str, max: usize, ) -> usize

Increment round-robin counter for an endpoint

pub fn consistent_hash(attribute: &str, num_variants: usize) -> usize

Generate a consistent hash for a request attribute

This is used for consistent hashing strategy to ensure the same request attribute (e.g., user ID) always gets the same variant.
