Cargo Features

[dependencies]
spartan = { version = "0.9.0", default-features = false, features = ["std", "multicore", "profile"] }
default = std

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

std default

Enables rust_backend of flate2, use_std of itertools ^0.10.0, std of byteorder and digest ^0.8.1 and std of merlin, rand, serde, sha3 ^0.8.2, and subtle

rand:

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

Required by nizk and snark binaries

multicore = rayon
profile = colored

Affects timer::CALL_DEPTH, timer::Timer

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.
