Summary

The docs for RwLock::try_write say:

This function will return the WouldBlock error if the RwLock could not be acquired because it was already locked exclusively.

I believe it should say "because it already has a shared or exclusive lock", based on how RwLock works (and based on my reading of the code). The sibling methods (read, write) clarify this detail correctly, and try_write's docs appear to be copied from try_read (where this description is correct), so I think this is just a small oversight from copying the description.

(For context, I was initially checking whether RwLock had some way to indicate that the lock was writer-locked, and this description confused me at first.)
