The letter comes as close to clearing him of collusion as one could expect. They couldn't find evidence of a conspiracy.
That's not just not indicting him. That's saying the evidence was not there, not that it was a close call but they decided not to. (The obstruction issue is, of course, a closer call.)
Assuming the letter is an accurate representation of Mueller's findings, I don't think that it's too inaccurate to say he was cleared of collusion.
It has been stated many times in this forum that, in the US, collusion is not a crime. If we accept that this is true then what purpose would there be to clear Trump of it?
