The error message says unused variable for 'stream'. looks to me like it is being used.
Thanks.
for stream in ... {
let stream = stream...
}
is eqiuiv to
for stream in ... {
let stream0 = stream...
}
Where is stream0
used?
The stream
created inside the loop is a distinct variable with its own scope. The variable you used was a Result <SocketAddr>
. The unused variable is a SocketAddr
.
OK. I think I understand now.
