Cargo Features

[dependencies]
cargo-unmaintained = { version = "1.5.0", default-features = false, features = ["cache-repositories", "on-disk-cache", "lock-index"] }
default = lock-index, on-disk-cache

These default features are set whenever cargo-unmaintained is added without default-features = false somewhere in the dependency tree.

cache-repositories = on-disk-cache
on-disk-cache default cache-repositories?
lock-index default = libc, windows-sys

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.

libc unix lock-index
windows-sys win lock-index
