singleton-registry 2.1.1

//! Integration tests for registering and retrieving primitive types and strings.
//!
//! This test demonstrates the basic usage of the singleton registry with
//! common Rust types like integers, floats, booleans, and strings.
//!
//! NOTE: All tests use #[serial] because they share the same registry (advanced).
//! Running them in parallel could cause interference.
