Cargo Features

[dependencies]
fasthash-sys = { version = "0.3.2", default-features = false, features = ["sse42", "aes", "avx2", "gen"] }
default = aes, avx, avx2, sse42

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

sse42 default
aes default avx avx2
avx avx2 default = aes
gen = bindgen

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.

bindgen build gen?
