Struct LearnerBuilder

pub struct LearnerBuilder { /* private fields */ }

Builder for creating configured Learner instances.

Provides a flexible way to construct Learner instances with custom configurations and paths.

Examples

// Build with explicit config
let config = Config::default();
let learner = Learner::builder().with_config(config).build().await?;

// Or from a config path
let learner = Learner::builder().with_path("~/.learner").build().await?;
