Cargo Features

[dependencies]
unrar-async = { version = "0.1.13", default-features = false, features = ["tokio", "async-std"] }
default = tokio

The tokio feature is set by default whenever unrar-async is added without default-features = false somewhere in the dependency tree.

tokio default = runtime-tokio
async-std = runtime-async-std

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.

runtime-async-std async-std?

Enables async-std

runtime-tokio tokio

Enables tokio
