It is denoted with the binary operator `as`. For instance, `println!("{}", 1 + 1.0);` would not compile, since `1` is an integer while `1.0` is a float. However, `println!("{}", 1 as f32 + 1.0)` should compile. The exercise [`using_as`](using_as.rs) tries to cover this. - -Rust also offers traits that facilitate type conversions upon implementation. These traits can be found under the [`convert`](https://doc.rust-lang.org/std/convert/index.html) module. -The traits are the following: - -- `From` and `Into` covered in [`from_into`](from_into.rs) -- `TryFrom` and `TryInto` covered in [`try_from_into`](try_from_into.rs) -- `AsRef` and `AsMut` covered in [`as_ref_mut`](as_ref_mut.rs) - -Furthermore, the `std::str` module offers a trait called [`FromStr`](https://doc.rust-lang.org/std/str/trait.FromStr.html) which helps with converting strings into target types via the `parse` method on strings. If properly implemented for a given type `Person`, then `let p: Person = "Mark,20".parse().unwrap()` should both compile and run without panicking. - -These should be the main ways ***within the standard library*** to convert data into your desired types. - -## Further information - -These are not directly covered in the book, but the standard library has a great documentation for it. - -- [conversions](https://doc.rust-lang.org/std/convert/index.html) -- [`FromStr` trait](https://doc.rust-lang.org/std/str/trait.FromStr.html) -- cgit v1.2.3
