Cargo Features

rtest = { version = "0.2.1", default-features = false, features = ["capture_tracing", "async"] }
default = async, capture_tracing

These default features are set whenever rtest is added without default-features = false somewhere in the dependency tree.

capture_tracing default = bytes, tracing-subscriber

Affects config::RunArgs.test_tracing_log_level

async default = futures-util, paste, tokio

Affects config::BuilderGenerator, config::RunConfig.runtime_builder

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.
