Crate nospin 

This crate provides non thread-safe versions of the primitives in std::sync and std::lazy suitable for use in single-threaded no_std environments.

Features

• Mutex, RwLock, Once/SyncOnceCell, and SyncLazy equivalents

• Support for no_std environments

• lock_api compatibility

• Upgradeable RwLock guards

• Guards can be sent and shared between threads

• Guard leaking

Relationship with std::sync

While spin is not a drop-in replacement for std::sync an effort has been made to keep this crate reasonably consistent with std::sync.

Feature flags

The crate comes with a few feature flags that you may wish to use.

• lock_api enables support for lock_api
