Cargo Features

async-wasi = { version = "0.2.0", default-features = false, features = ["async_tokio"] }
default = async_tokio

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

async_tokio default = tokio

Affects net::async_tokio, preview_1::async_poll, preview_1::async_socket

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.
