-Parses vector expression into the [`Vector`](struct.Vector.html).
-
-This parser operates on byte sequence instead of `&str` because of the fact that PromQL, like Go, allows raw byte sequences to be included in the string literals (e.g. `{omg='∞'}` is equivalent to both `{omg='\u221e'}` and `{omg='\xe2\x88\x9e'}`).
