template <typename RHS = ode_rhs_fn, typename State = vec<real>>
requires vector_space<State> && std::invocable<RHS &, real, const State &, State &>
basic_euler_steps<RHS, State> euler(RHS f, State y0, ode_params p = {});

Lazy forward Euler trajectory for \(\dot{y} = f(t, y)\).

f has the signature void(real t, const State& y, State& dy), and p supplies t0, tf and dt.
