Imports name this capability’s declared dependencies, which fune builds next to it in your project; each one links to its page.
use super::funejson::Value; ← the fune runtime: the JSON value the test vectors use; fune build keeps it only where a signature takes one
use super::math_rational_rational::{rational_from_value, rational_from_wide, rational_parts, rational_to_value}; ← rational, another function of this group · built into the same file, even by a slim install
