Merge pull request #464 from L-as/main 
Fix compilation with rustc 1.57.0
 2022-01-20 18:24:53 +00:00
Jack Grigg f5a8c9dff9 Depend on `rand_core` instead of `rand` 
All non-test code no longer depends on `OsRng`, instead requiring the
caller to provide it.

Fix compilation with rustc 1.57.0 
The type inference algorithm seems to have been simplified,
meaning that the combination of T::from(x.into()) doesn't work anymore.

In any case, the code was also incomprehensible to a human, as it's not clear
by which "route" it does the transformation. It took me a few minutes to
figure out it's a `u64`.

Jack Grigg 1556489a9f Remove usage of `FieldExt::rand` 
All APIs now take `R: RngCore` arguments instead of internally depending
on `rand::rngs::OsRng`.

Jack Grigg a62f9451d1 sha256: Fix `AssignedCell` `From` impls for `AssignedBits` and `Bits` 
zcash/halo2#337 had been updated to account for `AssignedCell`, before
the change to simplify its bounds was made. `AssignedCell` now requires
the `From` impls to take `&VR`.

This is a more secure way to distinguish the initial round from
the main rounds.

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.

Jack Grigg 353a07cef1 `ConstraintSystem::lookup`: Move lookup queries into a closure 
This matches `ConstraintSystem::create_gate`.

At the same time, we bind the input and table expressions together as a
"table map" by requiring the closure to return a vector of tuples. This
ensures they are always the same length.
