Cargo Features

[dependencies]
ethereum_hashing = { version = "1.0.0-beta.2", default-features = false, features = ["zero_hash_cache", "detect-cpufeatures"] }
default = detect-cpufeatures, zero_hash_cache

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

zero_hash_cache default = lazy_static

Affects ethereum_hashing::ZERO_HASHES_MAX_INDEX

detect-cpufeatures default = cpufeatures

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.
