Merge pull request #287 from zcash/remove-selector-rotations 
Remove rotations from Selectors
 2021-06-05 23:36:37 +01:00
Jack Grigg 0d8b3bab38 Remove rotations from Selectors 
Enabling selectors to be used in gates at non-zero rotations leads to
confusing gates, and inhibits our ability to create visualizations of
circuits. In most cases, a gate can be rearranged so that the selectors
have no rotation; in cases where cross-gate selector optimisations are
required, these can still be implemented using fixed columns.

Jack Grigg 6cf73391e8 Enable annotating individual constraints within gates 
The closure passed to `ConstraintSystem::create_gate` can now return:

- Tuples of `(&'static str, Expression<F>)`
- Anything implementing `IntoIterator` (e.g. `Some(Expression<F>)`)

Jack Grigg 47061ade3d dev: Report indices of unsatisfied constraints 
Now that gates may contain multiple constraints, we need to inform
developers about which specific constraints are failing within gates.

Jack Grigg 0f0dd8a26c Allow multiple polynomial constraints per gate 
This enables a gate such as ECC complete addition to define its
constraints in terms of a common set of queried columns.

Merge pull request #209 from zcash/ecc-gadget-fixedpoints 
Store `Loaded` chip state in chip
 2021-02-26 04:24:28 +13:00
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.
