Struct Config 

pub struct Config {
    pub format: Option<ByteFormat>,
    pub keys: KeysConfig,
    pub notifications: NotificationsConfig,
    pub gitignore: Option<bool>,
    pub cleanup_heuristics: Option<bool>,
}

Runtime configuration used by interactive and CLI components.

The configuration file is optional. If it cannot be found, defaults are used. See Config::load for details on fallback and error behavior.

Expected TOML structure:

format = "binary"

# Controls whether Git-ignored entry detection is enabled in interactive mode.
# Supported values: true, false.
# If unset, behavior defaults to true.
# gitignore = true

# Controls whether cleanup heuristics are enabled in interactive mode.
# Supported values: true, false.
# If unset, behavior defaults to true.
# cleanup_heuristics = true

[keys]
esc_navigates_back = true

[notifications]
scan_finished = true
delete_finished = true

Fields

format: Option<ByteFormat>

Byte count format to use when --format and DUA_FORMAT are not set.

keys: KeysConfig

Keybinding-related settings.

notifications: NotificationsConfig

Interactive completion-notification settings.

gitignore: Option<bool>

Whether Git-ignored entry detection is enabled.

Supported values: true and false. If unset, defaults to true.

cleanup_heuristics: Option<bool>

Whether cleanup heuristics are enabled.

Supported values: true and false. If unset, defaults to true.

Implementations

impl Config

pub fn load() -> Result<Self>

Load configuration from disk.

Behavior:

• If no platform configuration directory is available, returns defaults.
• If the config file does not exist, returns defaults.
• If the config file exists but cannot be read, returns an error with path context.
• If TOML parsing fails, returns an error with path context.

Unknown keys are ignored. Missing supported keys fall back to defaults.

pub fn default_file_content() -> &'static str

Default TOML content used when initializing a new configuration file.

pub fn path() -> Result<PathBuf>

Return the expected configuration file location for the current platform.

The path is:

• Linux/Unix: $XDG_CONFIG_HOME/dua-cli/config.toml (or equivalent fallback)
• Windows: %APPDATA%\\dua-cli\\config.toml
• macOS: ~/Library/Application Support/dua-cli/config.toml

Returns an error if the platform config directory cannot be determined.

Trait Implementations

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

where Config: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
