Struct DebugObserver 

pub struct DebugObserver;

A debugging callback which prints out the step, status, and any user data at the current step in an algorithm.

Usage:

use ganesh::traits::*;
use ganesh::algorithms::gradient_free::{NelderMead, NelderMeadConfig};
use ganesh::test_functions::Rosenbrock;
use ganesh::core::DebugObserver;

let problem = Rosenbrock { n: 2 };
let mut nm: NelderMead = Default::default();
let config = NelderMeadConfig::default();
let result = nm
    .process(
        &problem,
        &(),
        [2.3, 3.4],
        config,
        NelderMead::default_callbacks().with_observer(DebugObserver),
    )
    .unwrap();
// ^ This will print debug messages for each step
assert!(result.message.success());
