Struct ConfigBuilder 

pub struct ConfigBuilder { /* private fields */ }

Builder for creating a configuration from multiple sources.

ConfigBuilder allows users to specify multiple sources for configuration (e.g., CLI, files, environment variables) and merges their data.

Implementations

impl ConfigBuilder

pub fn new() -> Self

Create an empty configuration builder with no sources.

pub fn add_source<S>(self, src: S) -> Self

where S: ConfigSource + Send + Sync + 'static,

Add a configuration source.

Accepts any entity implementing the ConfigSource trait and adds it to the list of sources to be loaded.

pub fn load(self) -> Result<ConfigValue, ParserError>

Load and merge all configuration sources.

Sources are sorted by priority (highest first) and merged sequentially, ensuring that later sources override earlier ones.
