Yeah of course I was joking... the solution I provided does work for the "I
need a one-liner" mentality, though.
I believe this following solution fits your use case, and is simpler to
read too:
datalen := removedKeyken // removedKeyken must have been int32 in your
example.
if value != nil {
datalen = len(value)
}
