k256 = { version = "0.14.0-pre.2", default-features = false, features = ["std", "alloc", "arithmetic", "bits", "critical-section", "digest", "ecdh", "ecdsa", "expose-field", "hash2curve", "jwk", "pem", "pkcs8", "precomputed-tables", "schnorr", "serde", "sha256", "test-vectors"] }

default = arithmetic, ecdsa, pkcs8, precomputed-tables, schnorr, std

These default features are set whenever k256 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.
