Proof step 12 from proof bytes2int-len-one-01 (previous step)

bytes2int(bytes0) = 0, 0 ≤ band(b2i(by), 255), band(b2i(by), 255) < 128 ⊦ bytes0 = [], bytes0.first = i2b(0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 13:
⊦ bytes2int(bytes) = bits2int(bytes2bits(bytes))
Proof step 14:
bits2int(bytes2bits(bytes0)) = 0, 0 ≤ band(b2i(by), 255), band(b2i(by), 255) < 128 ⊦ bytes0 = [], bytes0.first = i2b(0)

Rule argument

name: bytes2int rotate: F subst: [bytes] → [bytes0]
