Cargo Features

[dependencies]
si7021-t-rh = { version = "0.1.6", default-features = false, features = ["sync", "async"] }

default = sync

The sync feature is set by default whenever si7021-t-rh is added without default-features = false somewhere in the dependency tree.

sync default

async = embedded-hal-async

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.
