There was a problem hiding this comment.
Might make more sense to use different NS/ND in the example.

Fixes #522.
Ideally, this PR is updated after PR #521 is merged to simplify the tests.
This PR implements the
TryFromtrait for creating aDequefrom a slice.Note the use of
unsafefor copying all bytes from the slice to theDequebuffer after ensuring that theDequebuffer has enough space.Also note the use of
ManuallyDropto ensure that any heap memory referred to by the element contents is not dropped at the end of this method since the elements in theDequebuffer will be pointing to it.
