Proof step 5 from proof fix-length-01 (
previous step
)
⊦ lastn(# bytes, bytes) = bytes
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 6
:
⊦ n = # bytes → lastn(n, bytes) = bytes
Rule argument
seq: ⊦ n = # bytes → lastn(n, bytes) = bytes subst: [bytes, n] → [bytes, # bytes] rotate: F spec: list-del inst: bytelist name: lastN-all
Additional information
Used terms: bytes, # bytes
