Cargo Features

nostd_async has no features set by default.

[dependencies]
nostd_async = { version = "0.6.1", features = ["cortex_m", "wfe"] }
cortex_m = cortex-m
wfe = cortex-m

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.

cortex-m cortex_m? wfe?
