Fixed outdated reference to `waker` argument; now futures are passed a `Context`, from which one can obtain a `waker`. Cleaned up explanation of what happens when you call `poll` on a completed future. It doesn't make sense to say that `poll` implementations can't cause memory unsafety; no safe function is ever allowed to cause memory unsafety, so why mention it here? It seems like the intent is to say that the `Future` trait doesn't say what the consequences of excess polls will be, and they might be bad; but that the usual constraints that Rust imposes on any non-`unsafe` function still apply. It's also oddly specific to say 'memory corruption' instead of just 'undefined behavior'; UB is a bit jargony, so the text should provide examples.
This directory contains the source code of the rust project, including:
rustcand its testslibstd- Various submodules for tools, like rustdoc, rls, etc.
