Cargo Workspaces

Workspaces let you manage multiple crates in a single repository. They share a common Cargo.lock and output directory, which makes builds faster and dependencies consistent.

Defining a Workspace

Create a top-level Cargo.toml:

[workspace]
members = [
  "cli",
  "core",
  "utils",
]

Each member is a normal Cargo crate in its own directory.

Why Use Workspaces?

• Share code between crates without publishing
• Keep one Cargo.lock for consistent dependency versions
• Build and test all crates together with cargo build or cargo test

Workspaces are ideal for larger Oxide projects, especially when you want to split libraries and binaries into separate crates.
