Struct GpioConfig

pub struct GpioConfig {
    pub pins: Vec<PinConfig>,
    pub config: SysConfig,
}

Fields

pins: Vec<PinConfig>

config: SysConfig

Implementations

impl GpioConfig

pub fn load(configs: &[String]) -> Result<GpioConfig, Error>

Load a GPIO Config from the system

This function will load the GPIO configuration from standard system locations as well as from the additional configs passed in via the configs parameter. Each parameter is expected to be a path to a config file in disk.

Under the covers, this function will attempt to discover configuration files in the following standard locations in order:

• /etc/gpio.toml
• /etc/gpio.d/*.toml
• configs (parameter)

Each config file found in these locations will be loaded and then they will be pulled together to form a unified configuration via the combine method.

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<GpioConfig, Error>

Load a GPIO config from the specified path

pub fn get_pin(&self, name: &str) -> Option<&PinConfig>

Get the pin with the provided name if present in this configuration

pub fn get_pins(&self) -> &[PinConfig]

Get a reference to all the pins in this config

pub fn get_symlink_root(&self) -> &str

Get the symlink root specified in the config (or the default)

pub fn update(&mut self, other: GpioConfig) -> Result<(), Error>

Merge other into self (takes ownership of other)

If in conflict, the other GPIO config takes priority.
