Cargo Features

[dependencies]
edition = { version = "1.0.1", default-features = false, features = ["rust-2015", "rust-2018", "rust-2021", "rust-2024"] }

default = rust-2015, rust-2018, rust-2021, rust-2024

These default features are set whenever edition 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.
