Cargo Features

[dependencies]
rrdb = { version = "0.0.2", default-features = false, features = ["rrdb", "cli"] }
default = rrdb

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

rrdb default = cli

Required by the binary

cli rrdb = atty, structopt

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.

atty cli?
structopt cli?
