Cargo Features

TendermintMachine has no features set by default.

[dependencies]
tendermint-machine = { version = "0.2.0", features = ["substrate"] }
substrate = sp-runtime

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.
