Implementations

impl Config

pub fn new() -> Result<Self>

Create a new config with defaults.

Errors

Will return an error if the default configuration validation fails.

pub fn load() -> Result<Self>

Load configuration from multiple sources with precedence:

1. Default values
2. Configuration file (if exists)
3. Environment variables
4. Provided overrides

Errors

Will return an error if the configuration file cannot be read or contains invalid configuration data.

pub fn load_from_file<P: AsRef<Path>>(path: P) -> Result<Self>

Load config from a file.

Errors

Will return an error if the file cannot be read or contains invalid configuration data.

pub fn load_with_provider<P: Provider>(provider: P) -> Result<Self>

Load config using a configuration provider.

Errors

Will return an error if the provider fails to load a valid configuration.

pub const fn shutdown_timeout(&self) -> Duration

Get the shutdown timeout as a Duration.

pub const fn force_shutdown_timeout(&self) -> Duration

Get the force shutdown timeout as a Duration.

pub const fn kill_timeout(&self) -> Duration

Get the kill timeout as a Duration.

pub const fn metrics_interval(&self) -> Duration

Get the metrics interval as a Duration.

pub const fn health_check_interval(&self) -> Duration

Get the health check interval as a Duration.

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

Validate the configuration.

Errors

Will return an error if any configuration values are invalid or missing required fields.

pub fn worker_threads(&self) -> usize

Get the number of worker threads to use.

pub const fn is_json_logging(&self) -> bool

Check if JSON logging is enabled.

pub const fn is_colored_logging(&self) -> bool

Check if colored logging is enabled.

pub fn builder() -> ConfigBuilder

Create a builder for this configuration.

impl Config

pub fn watch_file<F, P>(path: P, on_change: F) -> Result<RecommendedWatcher>

where F: Fn(Result<Self>) + Send + Sync + 'static, P: AsRef<Path>,

Start watching a configuration file and invoke a callback on changes. This uses the same loading path as load_from_file, so it will pick up any enabled fast-paths (e.g., mmap-config).

The returned watcher must be kept alive for notifications to continue.

Errors

Returns an error if the watcher cannot be created or the path cannot be watched.

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() -> Self

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.
