Remove explicit std::marker from Sized bound
...
Sized is always part of the prelude, and binding on std causes
compilation issues for no-std crates.

ff: Move pow_vartime back into Field trait
...
The only places we don't use constant u64 limbs, we use PrimeField::char
instead (except in a single test where we use a field element).
2020-05-02 18:54:02 +12:00
fb31d09218
ff: Remove Ord bound from PrimeField
...
ff_derive still implements Ord and PartialOrd for the fields it
implements, because pairing::bls12_381 internally assumes that those are
implemented. Once we delete that implementation, we will remove the Ord
and PartialOrd implementations from ff_derive.
2020-05-02 18:54:02 +12:00

ff: Add PrimeField::ReprEndianness associated type
...
This enables generic code to reliably operate on the bits of an encoded
field element, by converting them to and from a known (little)
endianness.
The BitAnd and Shr bounds on PrimeField are now removed, as users can
perform these operations themselves as needed.
2020-05-02 18:54:02 +12:00

ff: Remove frobenius_map from Field trait
...
It is only used internally in the bls12_381 crate, and field extensions
aren't exposed anywhere in the Zcash stack.
2020-05-02 16:07:48 +12:00
1761ebfb35
ff: Remove SqrtField trait
...
The sqrt() function is now part of the Field trait. ff_derive returns an
error on fields for which it does not support generating a square root
function.
Note that Fq6 and Fq12 in pairing::bls12_381 leave the function
unimplemented. They will be dropped once the migration to the bls12_381
crate is complete. The equivalent structs in that crate are not exposed.

- CommitmentTreeWitness::from_slice_with_depth is more idiomatic Rust.
