Trait Derivative 

pub trait Derivative<N: ComplexField + Copy, D: Dim, T: Clone>: FnMut(N::RealField, &[N], &mut T) -> Result<BVector<N, D>, UserError>
where
    DefaultAllocator: Allocator<N, D>,
{ }

A function that can be used as a derivative for the solver

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
