Proof step 37 from proof fix2rest-last (previous step)

# bytes0 = 1, bytes2int(bytes0 + by ') < 0 ⊦ (bytes0 + by ').rest = by '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 38:
⊦ bytes ≠ [] → (bytes + bytes0).rest = bytes.rest + bytes0
Proof step 39:
bytes0 ≠ [], # bytes0 = 1, bytes2int(bytes0 + by ') < 0 ⊦ bytes0.rest + by ' = by '

Rule argument

seq: ⊦ bytes ≠ [] → (bytes + bytes0).rest = bytes.rest + bytes0 subst: [bytes0, bytes] → [by ', bytes0] rotate: F spec: list inst: bytelist name: rest-01

Additional information

Used simplifier rules: ⊦ # [] = 0; Used terms: by ', bytes0
