Homu 9b0d4c91cb Auto merge of #171 - erickt:serde, r=hauleth
Add support for Serde 0.7.

Serde 0.7 dropped it's dependency on num, so this patch moves the implementations here. For the sake of a better implementation, this just serializes BigUint as a `Vec<u32>`, `BigInt` as a `(u8, Vec<u32>)`, `Complex<T>` as a `(T, T)`, and `Ratio<T>` as a `(T, T)`.

Josh Stone 5b2cb8df97 Simplify Integer dependant traits
- Integer only needs to require Ord explicitly, and then PartialOrd, Eq,
  and PartialEq come transitively.
- Generics on Integer can implicitly use all of those comparison traits.

This should not be a breaking change, as it doesn't actually change any
effective trait requirements -- only what's explicit for simplicity.

Homu d1adf45389 Auto merge of #162 - est31:add_checked_pow, r=cuviper
Add checked_pow function

Implements a `checked_pow` function which does the same as `pow`, just with overflow checks.

And, similar to #152 and #153, the function uses references instead of cloning.

Adds a little macro to spare code repetition. Its scoped to the function so nothing gets polluted.

Josh Stone 9ec4106a99 Merge pull request #154 from briansmith/optional-rand-rustc_serialize
Make `rand` and `rustc-serialize` dependencies optional.
2016-01-08 09:52:51 -08:00
Brian Smith 9e3e8552ac Make `rand` and `rustc-serialize` dependencies optional.
Previously, the `rand` and `rustc-serialize` dependencies were optional
except they were required for the `bigint` feature.

Make the dependency on the `rand` crate optional in all cases.
including when the `bigint` feature is selected. Some of the tests for
the bigint feature are randomized so, while `rand` is now an optional
dependency, it is a non-optional dev-dependency.

Similarly, make the dependency on the `rustc-serialize` crate optional
in all cases, including when the `bigint` feature is selected.

Josh Stone 22722ac55d pow: shift exp powers of 2 before accumulating
We can save a multiplication if we start the accumulation basically at
the first set bit of the exponent, rather than starting at one and
waiting to multiply.  We only need one itself if the exponent is zero,
which is easy to pre-check.

Josh Stone e8d948a3d2 Reduce the size of the BigUint pow benchmark
If a benchmark takes very long to run, it's harder to iterate on changes
to see their effect.  Even reduced to 100, this pow_bench takes around 8
seconds on my machine, and still shows meaningful optimization effects.
