Struct Config 

pub struct Config {
    pub port: u16,
    pub log_dir: PathBuf,
    pub log_level: String,
    pub retention_days: u32,
    pub extra_patterns: Vec<String>,
    pub foreground: bool,
    pub update: UpdateConfig,
}

Resolved runtime configuration for the OpenLatch daemon.

This struct is constructed by Config::load from the full precedence chain: CLI flags > env vars > config.toml > defaults.

Fields

port: u16

TCP port for the local daemon (default: 7443).

log_dir: PathBuf

Directory for audit and daemon logs.

log_level: String

Tracing log level (default: “info”).

retention_days: u32

Audit log retention in days (default: 30).

extra_patterns: Vec<String>

Additional regex patterns for secret masking (additive to built-ins, per D-03).

foreground: bool

When true, daemon runs in foreground without forking.

update: UpdateConfig

Update check configuration (UPDT-01 through UPDT-04).

Implementations

impl Config

pub fn defaults() -> Self

Return sensible defaults for all config fields.

pub fn load( cli_port: Option<u16>, cli_log_level: Option<String>, cli_foreground: bool, ) -> Result<Self, OlError>

Load configuration from the full precedence chain.

Precedence order (highest to lowest):

1. CLI flags (cli_* parameters — Some(value) overrides)
2. Environment variables (OPENLATCH_PORT, OPENLATCH_HOST, OPENLATCH_LOG_DIR, OPENLATCH_LOG, OPENLATCH_RETENTION_DAYS)
3. ~/.openlatch/config.toml (parsed, partial overrides)
4. Compile-time defaults

Errors

Returns OlError if the config file exists but cannot be parsed as valid TOML.

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.
