Function package_directives 

pub fn package_directives(
    package: &Package,
) -> Result<Vec<ConfigDirective>, RippyError>

Parse a package’s TOML into config directives.

For built-ins, parses the embedded TOML. For custom packages with extends = "<builtin>", first generates the base package’s directives, then appends the custom package’s directives (last-match-wins lets custom rules override base rules).

Errors

Returns RippyError::Config if the TOML is malformed, or RippyError::Setup if extends references an unknown or non-built-in package.
