Andreas Molzer cd0da1ae5e Fix num parsing for invalid multi-byte sign chars
Ensure that splitting the potential sign character from the remainder
respects UTF8 boundaries. This lets invalid characters fail correctly
with an error, instead of panicking.

108: int: document PrimInt trait r=cuviper a=dvdhrm

This documents the PrimInt trait, explains its intentions and features
as well as mentions its origins for future reference.

Closes #11.

104: Add inplace methods to `Zero` and `One` r=cuviper a=lcnr

Adds the following default implemented methods to `Zero` and `One`:

```rust
fn set_zero(&mut self) {
    *self = Zero::zero();
}
```

```rust
fn set_one(&mut self) {
    *self = One::one();
}
```

This allows for reuse of BigNums.

Samuel Tardieu fc4f1afdf6 Fix CheckedShl/CheckedShr documentation
Fix #57 and more:

- CheckedShl was hinting that None was returned on overflow rather than
  on too large a rhs.
- Ditto for CheckedShr.
- CheckedShr documentation erroneously indicated that a left shift was
  going to be performed instead of a right shift.

Ed McCardell abb51f9a09 Add wrapping shifts
Add traits `WrappingShl` and `WrappingShr` corresponding to the
standard library `wrapping_shl` and `wrapping_shr` methods. Implement
the trait on all primitive integer types as well as on `Wrapping`.

73: Avoid `as` casts in default FromPrimitive methods r=cuviper a=cuviper

Particularly, the default `from_f64` used `n as i64`, which has
undefined behavior on overflow, kind of defeating the purpose here.
Now we use a checked `to_i64()` for this, and even try `to_u64()` as a
fallback for completeness.

Also make similar changes to default `ToPrimitive`, but at least it
didn't have the same casting problem.

(All of the primitive implementations already do better, at least.)

Josh Stone bbbc2bd1d7 impl 128-bit numeric casts
This includes new conditional methods `ToPrimitive::{to_i128,to_u128}`
and `FromPrimitive::{from_i128,from_u128}`.  Since features can only be
additive, these methods must not cause a breaking change to anyone when
enabled -- thus they have a default implementation that converts through
64-bit values.  Types that can do better with a full 128-bit integer,
like bigint or floating-point, will probably want to override these.
