Cargo Features

[dependencies]
borrow_trait = { version = "0.1.1", default-features = false, features = ["std", "alloc", "atomic_refcell", "cell"] }

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

std default = alloc

alloc std
