Cargo Features

Rspec has no features set by default.

[dependencies]
rspec = { version = "1.0.0", features = ["expectest_compat", "clippy"] }
expectest_compat = expectest

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.
