Jack Grigg bd17c726ac Add a Selector type 
This currently just wraps a `Column<Fixed>`, but enables us to start
writing circuits that can later have their selector usage optimised.

Upstream Permutation struct into plonk::circuit

therealyingtong 4f17322c2d Allow Chip::load to return state that the Layouter will hold 
This enables chips that e.g. want to load multiple lookup tables into
the same columns to store state about where each table was layed out.

Merge pull request #202 from zcash/group-traits 
Migrate to group traits
 2021-02-22 13:37:02 -07:00
Jack Grigg b4ed5295fe Migrate to group traits 
The `Curve` trait is now `CurveExt: group::prime::PrimeCurve`, and
`CurveAffine` is now `CurveAffine: group::prime::PrimeCurveAffine`.

There is no `CurveAffine` trait in `group`, and it's a widely-used
trait in this crate, so we don't rename it to `CurveAffineExt`.
 2021-02-22 20:20:23 +00:00
Jack Grigg 55fb581f17 Define hash-to-curve over Curve, not CurveAffine 
This removes an unnecessary layer of indirection from the type system,
and ensures that these APIs depend on the halo2-specific trait with the
extensions we require.
