Cargo Features

ff = { version = "0.13.0", default-features = false, features = ["std", "alloc", "bits", "derive", "derive_bits"] }
default = bits, std

These default features are set whenever ff is added without default-features = false somewhere in the dependency tree.

std default = alloc
alloc std

Affects batch::BatchInvert

bits default derive_bits? = bitvec

Affects ff::FieldBits, ff::PrimeFieldBits

derive = byteorder, ff_derive

Affects ff::derive

derive_bits = bits

with MSRV 1.60 this could be merged into bits with ff_derive?/bits see PR#72 for more information.

Enables bits of ff_derive

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

bitvec bits
byteorder derive?
ff_derive derive? derive_bits?
