What is the difference between an option and a result in Rust?
In Rust, an option and a result are both types that represent the possibility of having an error or a successful value. However, some differences between them are:
An ‘Option’ represents the computational value that may or may not be present. For instance, it is used when there is a possibility that the function might not return a value while looking for an item within a collection. The option can either contain ‘Some (value)’ or ‘none,’ and it is generally used to avoid null pointer errors.
A ‘Result’ represents an operational result, which can either be a success or a failure with an associated error value (E) if it is a failure. The ‘result’ type is usually used in cases where a function might fail for several reasons, and thus the error cases can be handled in a structured way.
