pub trait BesselRatioFamily: BesselFamily { }Expand description
A family with a ratio kernel $F_\nu / F_{\nu-1}$ and its inverse, for
bessel_ratio and its three companions. Only
I today (the von Mises-Fisher quantities). A K ratio would be the next member.
Real vectors only, like the entries it serves: the ratio kernels compare and take absolute values along the real line.

This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
