Learning Rust — Workspace Setup

This short guide shows how this Learning_Rust workspace is structured and how the Cargo.toml files are wired up.

✅ Step 1 — Create Root Folder

Create your main learning folder and enter it:

mkdir Learning_Rust
cd Learning_Rust

✅ Step 2 — Workspace Cargo.toml (Root)

The root Cargo.toml declares this directory as a workspace and lists the three member crates:

[workspace]
resolver = "3"
members  = [
  "01-basic",
  "02-data_types_and_structures",
  "03-functions",
]

• The folder is a Cargo workspace.
• Each listed folder is a crate that lives inside the workspace.

✅ Step 3 — Current Workspace Layout

The workspace you are looking at is organized like this:

Learning_Rust/
  Cargo.toml                 <-- workspace (see members above)

  01-basic/
    Cargo.toml               <-- simple binary crate
    src/main.rs

  02-data_types_and_structures/
    Cargo.toml               <-- crate with many binaries
    01-scalar/
      main.rs
    02-compound/
      01-tuple.rs
      02-arrays.rs
      03-slices.rs
      04-strings.rs
    03-structs/
      01-structs.rs
      02-initialization_and_update.rs
      03-methods_and_associated_fn.rs
    04-enums/
      01-enums.rs
      02-enum_matching.rs
      03-methods.rs

  03-functions/
    Cargo.toml               <-- crate with three binaries
    01-functions.rs
    02-parameter_passing.rs
    03-return_values.rs

Inside 02-data_types_and_structures and 03-functions, the Cargo.toml files declare multiple [[bin]] targets so each file can be run as its own example.

✅ Step 4 — Useful Cargo Commands

• Build everything at once: cargo build --workspace
• Run a binary from 01-basic: cargo run -p chapter-01
• Run a specific example from data types: cargo run -p chapter-02 --bin tuples
• Run a specific example from functions: cargo run -p chapter-03 --bin return_values

Next steps

• Add dependencies per-crate in their Cargo.toml files.
• Use this layout as a template if you want to add more learning crates (e.g., 04-control_flow, 05-ownership), and remember to register them under [workspace].members in the root Cargo.toml.
