Setting up a Cargo workspace

Since we are going to create a new application, it would be nice if we could make the code for the our_application Rocket application work alongside this new application. Cargo has a feature called Cargo workspaces. A Cargo workspace is a set of different Cargo packages in a single directory.

Let's set up a Cargo workspace to have multiple applications in a single directory using the following steps:

1. Create a directory, for example, 01Wasm.
2. Move the our_application directory inside the 01Wasm directory and create a new Cargo.toml file inside the 01Wasm directory.
3. Edit the Cargo.toml file as follows:

   [workspace]
   members = [
     "our_application",
   ]

4. Create a new Rust application inside 01Wasm using this command:

   cargo new our_application_wasm

5. After that, add the new application as a member of the workspace in 01Wasm/Cargo.toml, as follows:

   members = [
     "our_application",
