Cargo Features

[dependencies]
lifetime = { version = "0.1.0", default-features = false, features = ["alloc", "macros", "unstable"] }

default = alloc

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

alloc default

macros = lifetime_proc_macros

unstable

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.
