5.4 Immutable Bytestrings

 (require rebellion/binary/immutable-bytes)
  package: rebellion

An immutable bytestring is a bytes? value that is immutable, in the sense of immutable?. The rebellion/binary/immutable-bytes module provides functions and predicates that always accept and return immutable bytestrings.

procedure

(immutable-bytes? v)  boolean?

  v : any/c
A predicate for immutable bytestrings. Implies bytes? and immutable?.
