改写ans short switch case表达式

I have such code block where I just increment counters:

switch fileInfo.RequestType {
case lib.WRITE:
    WriteCounter += 1
case lib.READ:
    ReadCounter += 1
}

It seems to me that this snippet doesn't look like a idiomatic golang code. Can it be done more short and "elegant"?

More idiomatic:

switch fileInfo.RequestType {
case lib.Write:
    writeCounter++
case lib.Read:
    readCounter++
}

I'm not really sure what elegant here mean. Maybe putting the case statement to be inline?

switch fileInfo.RequestType {
    case lib.WRITE: WriteCounter += 1
    case lib.READ: ReadCounter += 1
}

Writing style like above are valid, but it doesn't follow the gofmt standard.
