pub struct Config { /* private fields */ }

Implementations

impl Config

pub fn builder() -> ConfigBuilder

pub fn sources(&self) -> &[ConfigSourceInfo]

Returns source provenance in build order.

pub fn file_sources(&self) -> impl Iterator<Item = &Path>

Iterates only existing file sources used during build.

pub fn primary_file_source(&self) -> Option<&Path>

Returns the first existing file source used during build.

pub fn get<T>(&self) -> Option<T>

where T: DeserializeOwned + ConfigItem,

Retrieves a configuration section.

Returns

Some(T) if found, None otherwise.

pub fn expect<T>(&self) -> T

where T: DeserializeOwned + ConfigItem,

Retrieves a required configuration section, panicking if not found or invalid.

Panics

Panics if the configuration section is missing or cannot be deserialized. Recommended for critical configuration items that must be present for the application to function. For optional items, use get or get_or_default instead.

pub fn get_or_default<T>(&self) -> T

where T: DeserializeOwned + ConfigItem + Default,

Retrieves a configuration section, returning default if not found or invalid.

Returns

The section or its default.
