Function copperlace_ruleset_from_file 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn copperlace_ruleset_from_file(
    path: *const c_char,
    out_handle: *mut *mut CopperlaceRuleSet,
    out_error: *mut *mut c_char,
) -> c_int

Loads a configuration file and returns an opaque ruleset handle.

On success, writes a non-null handle to out_handle and returns COPPERLACE_OK. On failure, writes null to out_handle, writes an owned error string to out_error when provided, and returns a nonzero status code. Returned error strings must be released with copperlace_string_free.

Safety

path must point to a valid NUL-terminated UTF-8 string. out_handle must be a valid writable pointer when non-null. out_error must be valid for writing when non-null, and any returned error string must be released with copperlace_string_free.
