Hello, I am reading the Rust book How to Write Tests - The Rust Programming Language and have this directory structure for a project named hello_cargo. I get a compilation error that I wrote as comment above the code line. It cannot resolve the project name but this is what the Rust book does for the integration test, too. Can someone explain why this does not work? Test Organization - The Rust Programming Language src/ - main.rs - module1/ -- mod.rs -- submodule1/ --- mod.rs - module2/ -- mod.rs - lib.rs tests/ - integration_test.rs // test/integration_test.rs // compiler error: // failed to resolve: use of unresolved module or unlinked crate `hello_cargo` use hello_cargo::{module1, module2, module2::submodule1}; #[test] fn testmain() { assert_eq!(main::module1::mod1string(), "mod1string"); assert_eq!(main::module2::mod2string(), "mod2string"); assert_eq!(main::module1::submodule1::mod1string(), "submod1string"); //assert_eq!(main1::main1test(), "main1test"); }

I have a follow up question: I deleted lib.rs as you said. I have two crates, main.rs and main1.rs and a number of submodules in main.rs, this is the directory structure: tests/ - integrationtests.rs src/ - main.rs - module1/ -- mod.rs -- submodule1/ --- mod.rs - module2/ -- mod.rs - main1.rs //integrationtests.rs use main::*; // unresolved import: // unresolved module or use of unimported module "main1" use main1::*; #[test] fn testmain() { assert_eq!(main::module1::mod1string(), "mod1string"); assert_eq!(main::module2::mod2string(), "mod2string"); assert_eq!(main::module1::submodule1::mod1string(), "submod1string"); assert_eq!(main1::main1test(), "main1test"); } I followed the compiler suggestion and executed `cargo add main` but this throws an error for `cargp add main1`: `error: the crate `main1` could not be found in registry index.` Could you tell me what is wrong once more?

Because your file should look like this. You should not create mod module1 inside module1 file // module1.rs pub mod submodule1; pub fn greet() -> () { println!("greetings from module1."); } You also maybe create module in wrong file. I see you have both: main.rs and lib.rs main.rs is binary crate, lib.rs is library crate. If you have lib.rs file, you create all modules in lib.rs file. This is how your files should look. // lib.rs pub mod module1; // main.rs use hello_cargo::module1::greet; use hello_cargo::module1::submodule1::greetsubmodule1; fn main() { greet(); greetsubmodule1(); } You use "use hello_cargo::module1::greet;", because main.rs and lib.rs are diffirent crates, so you can't call modules in lib.rs from main.rs using "use crate::module1::greet;" // module1.rs pub mod submodule1; pub fn greet() -> () { println!("greetings from module1."); } // submodule1.rs pub fn greetsubmodule1() -> () { println!("greet from submodule1."); }

When you are putting content into a new file and using `pub mod module1` in `main` – you are creating `crate::module1`, when you are writing `pub mod module1 { … }` – you are creating another, nested, module. That's inherent ambiguity of English about “exclusive” vs “inclusive” “or”: book says you may do one or another, but you assumed you can do both… well, it's not a crime to do both – but compiler wouldn't magically recognize that it's “silly” to have `module1` inside of `module1` (compilers tend to not think, but follow instructions) thus you end up with `module1::module1`.
