Importing issues in cdylib

[HaramanJohal]

I am trying to fuzz some of my code but I am struggling with imports.

I have taken the following steps from the documentation:

1. cargo install cargo-fuzz
2. cd my_project
3. cargo fuzz init

but then when I try to import my modules into the file fuzz_target_1.rs I get various errors

If I try extern crate my_project (as in the docs) I get can't find crate
If I try use my_project I get unresolved import and no external crate my_project

Is there some other way I am supposed to access my code from the fuzz target?

cargo fuzz init has automatically included the following in my_project/fuzz/Cargo.toml:

[dependencies.my_project]
path = ".."

(I was under the impression that this means I can do something like use my_project)

If there is a more appropriate place for me to ask this question I am happy to direct it elsewhere
(I would be happy to update documentation myself if necessary once I understand how this works)

I'm sure this might be something really basic that I'm missing, thanks for your help!

This should work, the .. should be enough to make it work; we really can't say more without seeing the code of your project. All of this is just standard cargo functionality, cargo-fuzz just generates the files.

Thanks for the response, I've tracked down the issue to this line in my project's Cargo.toml

crate-type = ["cdylib"]

I verified this in a minimal example which I got working with cargo-fuzz. I found that adding this line causes the undeclared crate errors.

I guess cargo-fuzz doesn't work for this type of library?

Yeah you should add rlib to that list
