[dependencies]

async-runtime = async-std

Affects retry_fn::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.

tokio tokio-runtime?
async-std async-runtime?
