Make errors public about argmin HOT 5 CLOSED

Thanks to you!!

from argmin.

Hi!

Error and ArgminError should be public. I just tried the following, which works for me:

use argmin::prelude::*;

impl ArgminOp for MyProblem {
    type Param = f64;
    type Output = f64;
    type Hessian = ();
    type Jacobian = ();
    type Float = f64;

    fn apply(&self, p: &Self::Param) -> Result<Self::Output, Error> {
        Err(ArgminError::InvalidParameter {
            text: String::from("bla"),
        }
        .into())
    }
}

However, the ergonomics are far from ideal, I agree. I will think about this.
Alternatively, you should be able to implement your own errors if you want to.

Could you show me the compile error, please?

Which version are you using? The current master branch or 0.2.6? Your snippet suggests the master branch, but your problem suggests 0.2.6 ;)

I would suggest to use the current master branch, as the current release is quite old and outdated. I plan to publish a new release soon.

Perfect!!
I am so sorry, I got mixed the two versions (working on 0.2.6). Working on the master branch works as you say :)

So, case solved.
Happy to hear about the new release! :D

By the way, did you notice that the documentation is "broken"? I mean, from crates.io, the documentation link is broken. Is it a problem with docs.rs?

(I can open other issue for this if you want)

from argmin.

Glad I could help! I'm very sorry about the confusion!

Thanks for informing me about the broken documentation, I will investigate it :)
