Feature flags of decaf377_plus crate // Lib.rs

Cargo Features

[dependencies]
decaf377_plus = { version = "0.10.1", default-features = false, features = ["std", "alloc", "parallel", "arkworks", "ecc-group", "r1cs", "serde", "u32_backend"] }

This matches what ark-std (a library for no_std compatibility) does, having a default feature of std - without the ark-std std feature, decaf377 doesn't compile

default = arkworks, ecc-group

These default features are set whenever decaf377_plus is added without default-features = false somewhere in the dependency tree.

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.
