Cargo Features

ark-std = { version = "0.4.0", default-features = false, features = ["std", "parallel", "print-trace", "getrandom"] }
default = std

The std feature is set by default whenever ark-std is added without default-features = false somewhere in the dependency tree.

std default parallel? print-trace?

Affects rand_helper::test_rng

parallel = rayon, std
print-trace = colored, std

Affects perf_trace::inner


Enables std of rand


Option (enabled by default): without "std" rand uses libcore; this option enables functionality expected to be available on a standard platform.

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.

rayon parallel?
colored print-trace?
