Cargo Features

[dependencies]
async-std = { version = "1.13.0", default-features = false, features = ["std", "alloc", "unstable", "attributes", "tokio1", "tokio02", "tokio03", "io_safety", "docs", "kv-log-macro", "log", "surf", "futures-lite", "gloo-timers"] }

default docs? = async-global-executor, async-io, futures-lite, gloo-timers, kv-log-macro, log, pin-project-lite, std

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

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.
