6cca9327be Refactor bit iteration infrastructure: 
* `to_bits` -> `to_bits_le`
* `BitIterator` -> `BitIteratorLE` + `BitIteratorBE`
* `found_one`/`seen_one` -> `BitIteratorBE::without_leading_zeros`

0df0a15e1b Blake PRF & R1CS Boolean Refactor (#132) 
* refactor(r1cs-std/boolean): expose enforcing value less than functionality

* fix(r1cs-std/boolean): ensure num_bits is calculated correctly from the arg

40cf13b7b8 num_traits:: -> algebra:: 2020-01-18 18:26:45 -08:00
François Garillot
722a901ae7 [RFC] Convert identity functions in Field, Group, and {Projective,Affine}Curve traits with One/Zero traits from num_traits. 
- contributes to #50,
- depends on #53 and builds on it,
- due to coherence & requirements of `num_traits::{Zero, One}` to implement `std::ops::Add<Self, ..>` and (resp.) `std::ops::Mul<Self, ..>`, I've had to replace the afferent `impl<'a, P: ..> (Add|Mul)<&'a Self> for Group(Affine|Projective)<P>` by direct implementations on `Self`,
- I did not have to fight the borrow checker for this conversion => I think this hints arithmetic operations are called in contexts where the operand is owned,
- hence should this end up on a merge track, we may want to open an issue to convert the `impl<'a, P:..> (Neg|Sub|..)<&'a Self> for ..<P>` trait usage to direct `impl<P:..> (Neg|Sub|..)<Self> for ..<P>`
- the `impl AddAssign for GroupAffine<P>` in curves/models/short_weierstrass_jacobian.rs is provided to fit trait bounds, and without any guarantee of suitability for any particular purpose
- and that, even though I don't think it's used.
