Update bitvec requirement from 0.18 to 0.19

[dependabot-preview[bot]]

Updates the requirements on bitvec to permit the latest version.

Changelog

Sourced from bitvec's changelog.

0.19.0

This is a small patch release, but must be upgraded to a minor release because of a name change in public API and implementation change that should not, but may, affect public API.

Macro Constructor Implementation

The macros used to construct bitvec literals have had their implementation changed. The introduction of the BitArray type simplifies the construction of buffers from token sequences, so bits! now produces a BitArray on the stack rather than a hidden static.

Specifically, bits! changes its expansion from

{
  static BUFFER: &'static [T; N] = […];
  &BitSlice::<O, T>::from_slice(&BUFFER)[.. LEN]
}

to

(&BitArray::<O, [T; N]>::new([…])[.. LEN])

The test suite demonstrates that the compiler is able to correctly extend the lifetime of the BitArray temporary to match the lifetime of the produced reference. However, if you run into any issue where bits! calls that previously worked now fail due to an insufficiently-scoped temporary, please file an issue.

BitRegister Internal Trait

As BitMemory is now able to describe any integer element in memory, but BitOrder is still able to only operate on processor registers, a new trait BitRegister serves to distinguish memory-bus integers from register-integers. This trait provides no information other than its presence or absence.

BitOrder trait functions are modified to require it as the bound on their type parameters, rather than BitMemory. This name change is visible to users, and thus the reason for the minor release. BitRegister is conditionally implemented according to the supported registers on the target processor.

0.18.3

Per [Issue #75], the BitMemory trait has been loosened to exclusively describe integer types, and not be constrained to only the integers that can be used in

this is a patch release but it happens to touch a part of public API that nobody actually uses, thus, the minor

@myrrlyn Great. Looks like we are good to go then! 🎉
