launchdarkly-server-sdk 3.3.0

//! Types for implementing custom FDv2 data sources.
//!
//! This module is experimental and not subject to semantic versioning. Its API
//! may change in any release.
//!
//! # Examples
//!
//! Implement a custom synchronizer and add it to a data system.
//! ```

//!     DataSourceBuildContext, FDv2SourceEvent, FDv2SourceEventFuture, FDv2SourceResult,
//!     FDv2SynchronizerConfig, Selector, Synchronizer, SynchronizerFactory,
