Implementations

impl PromptLoader

pub fn load(&self, relative_path: &str) -> Result<String, PromptError>

pub fn load_merged(&self, paths: &[&str]) -> Result<String, PromptError>

Load and merge multiple prompt files, separated by newlines.

pub fn load_with_vars( &self, path: &str, vars: &HashMap<String, String>, ) -> Result<String, PromptError>

Load a prompt with variable substitution. Variables are {{key}} patterns in the template.

pub fn clear_cache(&self)

Clear the cache, forcing reload on next access.

pub fn base_dir(&self) -> &Path

Return the base directory this loader reads from.
