Cargo Features
[dependencies]
tm1637-gpio-driver = { version = "2.0.6", default-features = false, features = ["fourdigit7segdis", "dummy", "gpio-api-wiringpi", "gpio-api-gpio_cdev", "gpio-api-sysfs_gpio", "gpio-api-gpio"] }- default = dummy, fourdigit7segdis, gpio-api-gpio_cdev
-
default features:
"gpio_cdev" is recommended => because of this it's a default feature - fourdigit7segdis default
-
no dependencies; just used for conditional compilation
Affects
tm1637-gpio-driver::fourdigit7segdis… - dummy default
-
only useful for debugging/testing; for example if you are developing on your mac and want to breakpoint into a function; wiringpi won't work on Mac for example
- gpio-api-wiringpi = wiringpi
-
"gpio-api-${crate.name}"
mapping from feature to its dependencies - gpio-api-gpio_cdev default = gpio-cdev
- gpio-api-sysfs_gpio = sysfs_gpio
- gpio-api-gpio = gpio
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.
