Struct Config 

pub struct Config { /* private fields */ }

Configuration manager wrapping Figment.

Implementations

impl Config

pub fn new(opts: ConfigOptions) -> Result<Self, ConfigError>

Create a new configuration with the given options.

Errors

Returns an error if configuration loading fails.

pub fn merge_cli<T: Serialize>(self, cli_args: T) -> Self

Merge CLI arguments into the configuration.

Call this after parsing CLI args to add them as highest priority.

pub fn get_string(&self, key: &str) -> Option<String>

Get a string value.

pub fn get_int(&self, key: &str) -> Option<i64>

Get an integer value.

pub fn get_float(&self, key: &str) -> Option<f64>

Get a float value.

pub fn get_bool(&self, key: &str) -> Option<bool>

Get a boolean value.

pub fn get_duration(&self, key: &str) -> Option<Duration>

Get a duration value (parses strings like “30s”, “5m”, “1h”).

pub fn get_string_list(&self, key: &str) -> Option<Vec<String>>

Get a list of strings.

pub fn contains(&self, key: &str) -> bool

Check if a key exists.

pub fn unmarshal<T: DeserializeOwned>(&self) -> Result<T, ConfigError>

Deserialise the entire configuration into a typed struct.

Errors

Returns an error if deserialisation fails.

pub fn unmarshal_key<T: DeserializeOwned>( &self, key: &str, ) -> Result<T, ConfigError>

Deserialise a specific key into a typed struct.

Errors

Returns an error if deserialisation fails.

pub fn unmarshal_key_registered<T>(&self, key: &str) -> Result<T, ConfigError>

where T: DeserializeOwned + Serialize + Default + 'static,

Deserialise a specific key and auto-register it in the config registry.

Same as unmarshal_key but also records the section in the global registry for reflection. The type must implement Serialize + Default so the registry can capture both the effective and default values.

Errors

Returns an error if deserialisation fails. The section is only registered on success.

pub fn env_prefix(&self) -> &str

Get the environment variable prefix.

Trait Implementations

impl Debug for Config

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

Formats the value using the given formatter.
