Struct ConfigLoader 

pub struct ConfigLoader { /* private fields */ }

Configuration loader.

Implementations

impl ConfigLoader

pub fn new() -> Self

Create a new configuration loader with defaults.

pub fn file<P: AsRef<Path>>(self, path: P) -> Self

Specify a configuration file to load.

Multiple files can be specified; later files override earlier ones.

pub fn files<I, P>(self, paths: I) -> Self

where I: IntoIterator<Item = P>, P: AsRef<Path>,

Specify multiple configuration files.

pub fn with_validation(self, validate: bool) -> Self

Enable or disable validation after loading.

pub fn with_validator(self, validator: ConfigValidator) -> Self

Set a custom validator.

pub fn with_env(self, enabled: bool) -> Self

Enable or disable environment variable overrides.

When enabled (default), environment variables override config file values:

• OPENAI_API_KEY → sets API key for all LLM clients
• VECTORLESS_MODEL → sets default model
• VECTORLESS_ENDPOINT → sets API endpoint
• VECTORLESS_WORKSPACE → sets workspace directory

pub fn load(self) -> Result<Config, ConfigError>

Load the configuration.

Behavior

1. Start with default configuration
2. Load and merge each specified file (in order)
3. Apply environment variable overrides (if enabled)
4. Validate configuration (if enabled)

Errors

Returns an error if:

• A specified file doesn’t exist
• A file can’t be parsed as valid TOML
• Validation fails (when enabled)
