Well, if you do not need to care about performance everything can be extremely simple indeed. Let me show you some data structure in coq/rocq while switching off notations and diplaying low level content.

Require Import String.

Definition hello: string := "Hello world!".

Print hello.

hello = String (Ascii.Ascii false false false true false false true false) (String (Ascii.Ascii true false true false false true true false) (String (Ascii.Ascii false false true true false true true false) (String (Ascii.Ascii false false true true false true true false) (String (Ascii.Ascii true true true true false true true false) (String (Ascii.Ascii false false false false false true false false) (String (Ascii.Ascii true true true false true true true false) (String (Ascii.Ascii true true true true false true true false) (String (Ascii.Ascii false true false false true true true false) (String (Ascii.Ascii false false true true false true true false) (String (Ascii.Ascii false false true false false true true false) (String (Ascii.Ascii true false false false false true false false) EmptyString))))))))))) : string

You know you could just define the verified specs in lean and if performance is a problem, use the lean spec to extract an interface and tests for a more performant language like rust. You could at least in theory use Lean as an orchestrator of verified interfaces.
