Cargo Features

[dependencies]
linux-kcapi = { version = "0.1.1", default-features = false, features = ["rand_trait"] }
default = rand_trait

The rand_trait feature is set by default whenever linux-kcapi is added without default-features = false somewhere in the dependency tree.

rand_trait default = rand_core

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.
