What is pub use in Rust?

pub use re-exports an item publicly from your module, letting others import it from your crate root without digging into subpaths.

How do I add a dependency like rand to my Rust project?

Edit Cargo.toml: add rand = "0.8.5" under [dependencies], run cargo build — it fetches from crates.io.

Should I use nested paths or * for Rust imports?

Nested paths for grouping common prefixes; avoid * in prod to keep scopes clean and traceable.
