Cargo Features

hv-cell has no features set by default.

[dependencies]
hv-cell = { version = "0.1.0", features = ["track-leases"] }
track-leases = hv-lease-tracker

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.
