Also update to use https instead of http. This avois mixed content
degradation on docs.rs.
The doc root URLs are correct as they are, the URL does not include the
crate name itself.
Rust 1.4 through 1.7 will issue warnings that `pub extern crate` does
not work as expected, although it appears to be fine. But Rust 1.8 and
later issue `#[warn(private_in_public)]` for `pub use num_foo as foo` if
that crate isn't public, and that's headed toward a hard error.
@bluss suggested instead `pub mod foo { pub use num_foo::*; }`, which
I thought I had tried before, but it appears to work fine on all
versions of Rust. Let's do it!
A small downside is that docs for `num::foo` now just show the wildcard
reexport, instead of direct documentation, but at least there's a link
to follow to the sub-crate.
It's a breaking change that `num::num_foo` paths are no longer public,
but we didn't really want those exposed in the first place. I consider
this minor -- people should either use the `num::foo` module as before
the split-up, or use the `num_foo` crate directly.
Fixes#189.
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)`.
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.
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.
Before:
test pow_bench ... bench: 8,267,370 ns/iter (+/- 93,319)
After:
test pow_bench ... bench: 7,506,463 ns/iter (+/- 116,311)
The hidden "mod test" layout of the first example has been broken for a
while, but it wasn't noticed because rustdoc wasn't passing any features
at all. That was fixed in rust-lang/rust#30372, and now we need to get
our ducks in a row too.
Making bignum optional allows skipping the rustc-serialize and rand
dependencies too, and it makes a big difference in num's build time.
With default (all) features, clean build time including dependencies: 27
seconds.
With no default features, clean build time including dependencies (none):
5 seconds.
Along the way, this commit also rationalizes the traits a bit more.
Moving to stable required vendoring a couple of minor things (notably,
radix formatting).
The code was performing an extra squaring of the base, which might
trigger an arithmetic overflow that doesn't matter to the result. Now
this squaring is only attempted when enough exp remains to need it.
A new doctest tries pow(6u8, 3), where an extra square would exceed 256.
