Cargo Features

[dependencies]
par = { version = "0.3.9", default-features = false, features = ["runtime-tokio", "examples"] }
default = examples

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

runtime-tokio examples = tokio

Affects runtimes::tokio

examples default = fastrand, runtime-tokio, tokio-tungstenite

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.
