How to read text from a file | Rust Language

Read all bytes from a reader into a new String with std::io::read_to_string
The match expression handles Ok and Error conditions.

Further reading :
More about "Ok" and "Err" - they are made from Result :

🔗 https://doc.rust-lang.org/nightly/std/result/enum.Result.html
🔗 https://www.becomebetterprogrammer.com/rust-generic-error-types/

Functions return Result whenever errors are expected and recoverable. In the std crate, Result is most prominently used for I/O.

(Result T, E is a common data type that allows propagating Rust errors without necessarily crashing the Rust program unless the program panics).
