Please try building something like Kubernetes in Rust instead of Go and you will realize “Rust” is a a complicated language (worse than complex). let secret_number = rand::thread_rng().gen_range(1, 101); This code contains a lot of information, so let’s go over it line by line. Rust has a few built-in number types; the u32 seen here is an unsigned, 32-bit integer. happens if next week version 0.5.6 of the But by default, Cargo will only look for versions greater than At this point, you would also notice a change in your Note: You won’t just know which traits to use and which methods and functions program is doing exactly what we told it to do: ask for another guess forever!

Type inference can handle this for// A string slice – an immutable view into another string// The string buffer can be statically allocated like in a string literal// or contained in another object (in this case, `s`)// A slice – an immutable view into a vector or array// This is much like a string slice, but for vectors// A tuple is a fixed-size set of values of possibly different types// A struct with unnamed fields, called a ‘tuple struct’// This is defined in the standard library as `Option`// Traits (known as interfaces or typeclasses in other languages) //// Owned pointer – only one thing can ‘own’ this pointer at a time// This means that when the `Box` leaves its scope, it can be automatically deallocated safely.// Here, `now_its_mine` takes ownership of `mine`. You’ll build a few projects along the way, and by the end, you’ll have a solid grasp of the language.
