325: Implement assign_from_slice r=cuviper
This commit implements `assign_from_slice(..)` for `BigUint` and `BigInt`. `assig_from_slice` is for performance : it allows to reassign a value to a `BigInt` or a `BigUint` without useless reallocations. It would be useful for loops for example. I need it to implement the Toom-3 algorithm.
I also added a missing test for `BigInt::from_slice(..)`.
323: Add CI badge r=cuviper
324: Add CI badge r=cuviper
This adds the CI badge to the pages on crates.io, #323 adds it to the README. Sorry for the separate PRs, but I didn't feel like forking and cloning the repository down to my laptop and simply used the GitHub online editor instead :-)
317: Feature/complex from str r=cuviper
This commit adds a basic parser for Complex types in Cartesian form, per https://github.com/rust-num/num/issues/289. It will take numbers of the form `a + bi`, `ai + b`, `a - bi`, `ai - b`, `a`, or `ai`. At least one space between the real/imaginary parts and the operator is mandatory; without bringing in a dependency on some regex crate, it's nontrivial to handle cases like, e.g., 0.217828e+1+31.4159E-1, or a similar case with polar coordinates. I could work on these issues later if you like.
320: complex: implement real ops directly r=cuviper
It's more efficient to implement these without creating an intermediate
complex value -- at the least, we don't have to rely on the compiler
optimizing out zero-ops.
274: Implement OpAssign for Complex r=cuviper
Design choice: Use by-value forms of OpAssign and use Clone to forward the reference arguments. That matches what the other traits do (for example Add).
Design choice: The complex += complex operation needs Add, not just AddAssign. The complex += real operation can use just AddAssign. You could just use Add for both, not sure which way is preferable.

313: Scalar operations across all integer types r=cuviper
With my apologies for opening a new PR, and also for the 8 month delay, this continues the work started in #237 - the discussion there outlines the goals I was aiming for. I suppose this supersedes that PR and the other one can now be closed.
This PR adds support for Add, Sub, Mul, Div and Rem operations involving one BigInt/BigUint and one primitive integer, with operands in either order, and any combination of owned/borrowed arguments.
314: Derive ToPrimitive for enums r=cuviper
I had to double the compile fail tests, as they will bail on the first error.
I have some ideas for more complex to/from primitive derives (with inner values that implement to/from primitive), but I'll save those for a future PR.
