I want to use a struct called Client that exists in examples > client > mod.rs in my model.rs file. My package name is CratesTest in the Cargo.toml.

I tried this in my model.rs:

extern crate CratesTest;

fn main() {
    CratesTest::Client::new(/*snip*/)
}

I get the error:

error[E0433]: failed to resolve: could not find `Client` in `CratesTest`
let client = CratesTest::Client::new(...
                         ^^^^^^ could not find `Client` in `CratesTest`

I also tried using mod client; but it doesn't bring it into scope.

    I'd say there's an inversion of dependency here: it's reasonable for your examples to depend on your library, but why would your library depends on the examples? – Jmb Nov 06 '19 at 10:31

    From [the documentation](https://doc.rust-lang.org/cargo/reference/manifest.html#examples): "Files located under examples are example **uses** of the functionality provided by the library" (emphasy mine). Examples use the library, not the reverse. – Denys Séguret Nov 06 '19 at 10:51
  • @Jmb I don't think there's another answer that what you said. You should transmute your comment into an answer – Denys Séguret Nov 06 '19 at 10:54

I'd say there's an inversion of dependency here: it's reasonable for your examples to depend on your library, but why would your library depend on the examples? As pointed out by Denys Séguret, the documentation states:

Files located under examples are example uses of the functionality provided by the library

so examples use the library, not the reverse.
