//! This example shows how you can use the [`tracing-mutex`] crate as a drop-in replacement for the
|
|
//! parking_lot crate. By default, `tracing-mutex` offers a set of type aliases that allows you to
|
|
//! use cycle-checking in development, and raw primitives in release mode, but this way, you can
|
|
//! even remove the dependency altogether, or hide it behind a feature.
|
|
//!
|
|
//! You can use whatever conditional compilation makes sense in context.

// deadlock tracing, so no need to use the automatic selection.
