Function soil_register_types 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn soil_register_types(
    runtime: *mut SoilRuntime,
    desc_json: *const c_char,
    err: *mut *mut SoilError,
) -> c_int

Register types from descriptor JSON (see descriptor_json). Returns 0 on success, nonzero with *err set on failure.

Safety

runtime is a live runtime; desc_json is a NUL-terminated UTF-8 string; err is null or a valid out-pointer.
