What4.Expr.StringSeq

Description

A simple datatype for collecting sequences of strings that are to be concatenated together.

We intend to maintain several invariants. First, that no sequence is empty; the empty string literal should instead be the unique representative of empty strings. Second, that string sequences do not contain adjacent literals. In other words, adjacent string literals are coalesced.
