A Go library providing efficient read-write mutexes with trylock, timeout, and no-starvation mechanisms.
go-lock is a Go library that implements advanced read-write mutexes with additional functionality beyond the standard sync package. It solves problems where traditional mutexes can cause system deadlocks or performance issues by providing non-blocking trylock mechanisms, timeout support, and starvation-free read-write locks.
Go developers building high-concurrency applications who need more control over locking behavior than provided by native sync.RWMutex, particularly those dealing with potential deadlock scenarios or requiring non-blocking lock acquisition.
Developers choose go-lock for its starvation-free read-write locks and flexible trylock mechanisms that prevent system blocking, offering better control over resource contention compared to standard Go synchronization primitives.

Provides TryLock, TryLockWithTimeout, and TryLockWithContext methods, enabling non-blocking and time-bound lock attempts to prevent deadlocks, as shown in the example code.
Implements fair read-write mutexes ensuring neither readers nor writers are indefinitely blocked, addressing common resource starvation issues in concurrent programming.
Offers CASMutex and ChanMutex with different performance characteristics, allowing developers to select based on their specific latency and allocation needs, per benchmark data.
Includes detailed benchmarks comparing against native sync.RWMutex and other implementations, helping developers make informed performance decisions.
Benchmarks show CASMutex is significantly slower (186 ns/op vs 27.4 ns/op for native sync.RWMutex) and involves memory allocations, which may impact high-throughput applications.
Lacks support for advanced features like recursive locking or priority inheritance, which might be required in complex concurrency scenarios not covered by the README.
Introduces a third-party dependency for core synchronization, increasing maintenance burden and potential breakage compared to relying solely on the standard library.
