Cargo Features

scroll = { version = "0.11.0", default-features = false, features = ["std", "derive"] }
default = std

The std feature is set by default whenever scroll is added without default-features = false somewhere in the dependency tree.

std default
derive = scroll_derive

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.
