Is it possible to use RWMutex to make writing non-synchronized?

RWMutex in Go is designed for synchronizing access to data, allowing multiple readers to read simultaneously, but blocking writes while reading, and vice versa.

Using RWMutex to make a write "asynchronous" (i.e., non-blocking or asynchronous) is not possible. RWMutex provides strictly synchronous access control:

• When calling Lock() for writing, the goroutine is blocked if there are active readers or writers.
• When calling RLock() for reading, the goroutine is blocked if there is an active writer.

If asynchronous writing is needed, other mechanisms should be used, such as:

• Channels for passing data to a separate goroutine that performs the write.
• Specialized data structures or libraries with non-blocking algorithms.

Example of using RWMutex:

var mu sync.RWMutex
var data int

func readData() int {
    mu.RLock()
    defer mu.RUnlock()
    return data
}

func writeData(val int) {
    mu.Lock()
    defer mu.Unlock()
    data = val
}

Here, reading and writing are synchronized, but the write is not "asynchronous".
