Fields

device: Option<String>

Default device address

format: Option<String>

Default output format

no_color: bool

Disable colored output

fahrenheit: bool

Use Fahrenheit for temperature

inhg: bool

Use inHg for pressure (instead of hPa)

bq: bool

Use Bq/m³ for radon (instead of pCi/L)

timeout: Option<u64>

Connection timeout in seconds

aliases: HashMap<String, String>

Device aliases (friendly name -> device address)

last_device: Option<String>

Last successfully connected device (auto-updated)

last_device_name: Option<String>

Name of the last connected device (for display)

behavior: BehaviorConfig

Behavior settings for unified data architecture

gui: GuiConfig

GUI-specific settings

Implementations

impl Config

pub fn path() -> PathBuf

Get the config file path.

Checks ARANET_CONFIG_DIR first, then falls back to the platform config directory.

pub fn load() -> Result<Self>

Load config from the default path.

Returns an error if the file exists but cannot be read or parsed.

pub fn load_or_default() -> Result<Self>

Load config from the default path, returning defaults when the file is absent.

Returns an error if the file exists but cannot be read or parsed.

pub fn load_from_path(path: &Path) -> Result<Self>

Load config from an explicit path.

pub fn load_from_path_or_default(path: &Path) -> Result<Self>

Load config from an explicit path, returning defaults when the file is absent.

pub fn load_or_default_logged() -> Self

Load config from the default path, logging a warning and falling back to defaults on error.

This helper is for non-fatal UI paths that should remain usable while still surfacing broken config files in the logs.

pub fn save(&self) -> Result<()>

Save config to file

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
