If it helps you can even put it on it’s own line, or at the beginning of lines, etc… It doesn’t “need” to go at the end, though rustfmt will move it there, but yeah, it’s just another binary operator like + or whatever. ^.^
This is even baked into languages like OCaml, where:
left ; right
It exactly identical to (with warnings/errors enabled):
let () = left in right
Where it even enforces that the left must be a statement with a useless unit value. 
Then again, in rust instead of doing blah at the end you can always do return blah;, which is technically an early return with a no-op expression as the ‘right’ operand after it (which seems a bit messy to me, lol). ^.^
