Summary
Rust integration tests can leverage RAII and the `testcontainers-rs` crate to manage Docker containers for test infrastructure, eliminating the need for built-in setup/teardown. By wrapping container lifecycle in a struct with a `Drop` implementation that handles async cleanup via a blocking thread hack, tests become fully isolated and parallelizable. This pattern works around Rust's lack of native setup/teardown and concurrent test execution constraints.
