default = async-std-runtime, auth-oauth2, compression, tokio-runtime: These default features are set whenever pulsar is added without default-features = false somewhere in the dependency tree.

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.
