1//! This crate contains the LaunchDarkly Rust SDK feature flag evaluation engine.
2//!
3//! Normal use of the Rust SDK does not require referencing this crate directly. It is used internally
4//! by the SDK, but is published and versioned separately so it can be used in other LaunchDarkly
5//! components without making the SDK versioning dependent on these internal APIs.
