Programming Languages MAKING THINGS RUN
Rust concepts Crates Rust stores libraries of existing functions in Manifest Crates needed for a program are defined in the manifest Cargo.toml Text file [package] name = "pi version = "0.1.0 edition = "2021 # See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html [dependencies] rand = "0.8.5"
Manifest Various information about your program, versions, authors, etc Basic manifest automatically generated by cargo build pi Found in project directory, pi cd pi
Manifest Edit Cargo.toml with any text editor, e.g. Notepad Add additional crates to the [dependencies] section <name of crate>= <version number> eg rand = 0.8.5 Find the most recent version from https://crates.io/crates Search by name of crate, e.g.rand Find the most recent version number, e.g.0.8.5 Add the crate name + version number to manifest [package] name = "pi version = "0.1.0 edition = "2021 # See more keys and their definitions at . [dependencies] rand = "0.8.5 cd Save!
Rust concepts In your project directory cargo build After (possibly a long delay) cargo will update its crates Now you can run your program cargo run Optionally Executable pi.exe will be found in the target directory
Rust manifests Executable pi.exe Can now be copied anywhere It will run independently i.e. not need the Rust system
Rust - Annoying Habits cargo tries to remember what you previously compiled Even if you have updated the default main.rs Containing the Hello world program!! In this case, clean its memory cargo clean p pi Build and run again cargo build cargo run
