Struct Loader 

pub struct Loader { /* private fields */ }

Helper for layering user overrides over the built-in defaults.

Implementations

impl Loader

pub fn new() -> Self

Start a loader seeded with the embedded defaults.

pub fn set_override<I>(self, key: &str, value: I) -> Result<Self, ConfigError>

where I: Into<ValueKind>,

Apply a single key/value override (useful for CLI settings).

pub fn build(self) -> Result<LexConfig, ConfigError>

Finalize the builder and deserialize the resulting configuration.
