* initial draft implementation * change name to follow rust convention. * revert use of HasTargetBytes instead of HasMutatorBytes for BytesSubInputMut * clippy * nostd * clippy * clippy * * HasLen required if implementing HasTargetBytes. * Added a checked version of the read to slice. * clippy * fix name. better doc. * added a common bytes trait for HasTargetBytes and HasMutatorBytes. * change interface * fix tests * clippers * use byte slice for subbytes * adapt to main * fix doc * mut sub slice version. return subinput to old state, and add subslice stubs * better api, doc fixes. * Don't clone, reshuffle * Move and rename * Uh-oh * move to bolts. rename things. * nostd * format * alloc * fix doc --------- Co-authored-by: Dominik Maier <domenukk@gmail.com> Co-authored-by: Dominik Maier <dmnk@google.com>
