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.

318: Add cargo keywords and categories. r=cuviper

Fixes #306. Suggestions welcome for better keywords/categories, though there is a limit of 5 of each.

bors[bot] bcccab17dd Merge #311 
311: rational: make sure Hash agrees with Eq r=cuviper

We can't use a derived `Hash` when we have a manual `Eq`, because we
need to uphold the invariant `a == b` → `h(a) == h(b)`.  Since `Eq`
doesn't require them to be in reduced form, `Hash` also needs to be
normalized.

Fixes #310.

315: Fix float NaN positive/negative assumptions r=cuviper

These are the minimal assumptions to make about `NaN`. Fixes part of #312 (but not the `next` branch).

Eduardo Pinho 15f9334955 De-generalize `twos_complement' helper function 2017-06-20 01:31:49 +01:00
Eduardo Pinho 61cfdc37b3 BigInt two's complement adjustments 
- rename `_twos_complement_` methods to just `_signed_`
- make `from_` variants take &[u8]
- refactor helper functions twos_complement (they take byte slice but use a generic function underneath)
- fix issues in `to_signed_` functions (only two's complement negative numbers; perform byte extension where needed)
- add tests to `to_signed_` methods
