Answer 1

I think you may have misunderstood package management with cargo. Since in3 is a library and not a binary crate, you cannot install it.

cargo install does not install dependencies like npm install or pip install does. cargo install will install binaries into your local filesystem (typically $HOME/.cargo/bin) for you to run.

Cargo will resolve dependencies for you when you cargo run/check/build. You do not need to install dependencies.

You may want to start a new folder structure and try the following:

1. Run cargo init. This will create a new binary package
2. Edit Cargo.toml and add the in3 dependency and version.
3. Modify the main.rs file to use the in3 library.
4. Run the program with cargo run. You will notice that cargo is resolving various dependencies while compiling your program.
