Rust is a systems programming language pursuing the trifecta: safety, which is guaranteed at compile time; fearless concurrency, which is a lot easier when things are safe; and blazingly fast speed due to zero-cost abstractions and other nice things.

Exceptions or Errors (in rust) is a state of a program when a piece of code does not execute as it should. It may be due to a resource that should be available at this time but is not.

Arrays in Rust are not dynamic, array size and type of data it will hold need to be defined before compilation. Vector are the dynamic arrays in Rust.

Array is collection of same type items. Arrays in Rust are different from other programming languages because they must contain a predetermined number of values.

Loops is a way to execute a portion of code again and again to meet a certain objective. Rust provides different looping functionalities for different situations and settings.
