storage_zip

This crate offers utility functions for zipping Options and Results into tuples.

It is instead to be used when different actions yields Options or Results values but the program flow can only proceed if all of them are Some or Ok. When used with Result, it requires that all the Results being zipped have the same error type and it will evaluate to the first error or to the tuple with all the Ok values.

With the crate you can do:

```rust use storage_zip::OptionZip;

let optionvalueone = Some(0); let optionvaluetwo = Some(5);

let zippedoptions = Option::zip(optionvalueone, optionvaluetwo); asserteq!(zipped_options, Some((0, 5))); ```

The crate also provides zip functions with more arguments:

```rust use storage_zip::ResultZip; use std::fs::File; use std::io;

let f1 = File::open("file1"); let f2 = File::open("file2"); let f3 = File::open("file3");

let zipped_result: Result<(File, File, File), io::Error> = Result::zip3(f1, f2, f3); ```
