Cargo Features

tf_r2r has no features set by default.

[dependencies]
tf_r2r = { version = "0.2.0", features = ["ros2"] }
ros2 = r2r

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.

r2r ros2?
