Cargo Features

[dependencies]
bme280 = { version = "0.5.1", default-features = false, features = ["with_defmt", "with_std", "sync", "async", "serde"] }
default = sync

The sync feature is set by default whenever bme280 is added without default-features = false somewhere in the dependency tree.

with_defmt = defmt
with_std = derive_more
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.

A generic serialization/deserialization framework
