A small Rust library simulation used for learning Rust and practicing basic ownership/borrowing and simple program structure.

This project contains a minimal command-line simulation of a library with:

• Book structs (title, author, pages, available)
• Patron structs (name, id)
• Library with methods to add/display/checkout/return books and query availability
• Simple daily action simulation (checkout / return / browse)

Requirements

• Rust and Cargo (stable toolchain)

Build and run

cd library_sim
cargo build
cargo run

The program prints the library catalog, simulates several days of user actions (checkouts, returns, browsing), and prints availability statistics.

• Cargo.toml — Cargo manifest
• src/main.rs — main program and core logic

• Add books using Library::add_book() or by editing src/main.rs sample data.
• Run cargo run to execute the simulation. Output includes daily actions and final availability counts.

Small fixes and improvements welcome. Suggested tasks:

• Add tests for Library methods
• Improve random action weighting
• Add CLI options for number of days, seed, or input file
