Cargo Features

[dependencies]
hooks-core = { version = "3.0.0-alpha.6", default-features = false, features = ["futures-core"] }
default = futures-core

The futures-core feature is set by default whenever hooks-core 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.
