Cargo Features

[dependencies]
cumulus = { version = "0.0.6", default-features = false, features = ["pedantic", "yaml"] }
default = yaml

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

pedantic
yaml default = serde_yaml

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.
