p521 = { version = "0.13.3", default-features = false, features = ["std", "alloc", "arithmetic", "digest", "ecdh", "ecdsa", "getrandom", "hash2curve", "jwk", "pem", "pkcs8", "serde", "sha512", "voprf", "test-vectors"] }

default = arithmetic, ecdsa, getrandom, pem, std

These default features are set whenever p521 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.

rand_core getrandom

serdect serde?
