Cargo Features

[dependencies]
nrf24l01 = { version = "0.2.0", default-features = false, features = ["rpi_accel", "sysfs_gpio"] }
default = sysfs_gpio

The sysfs_gpio feature is set by default whenever nrf24l01 is added without default-features = false somewhere in the dependency tree.

rpi_accel = rppal

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.
