# storage_zip

This crate offers utility functions for zipping `Option` and `Result`

values into tuples.

This is intended to be used when different actions yields multiple

`Option` or `Result` values but the program flow can only proceed if

all of them are `Some` or `Ok`.

When it is used with a `Result` based value, it requires that all the

`Result` values 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 option_value_one = Some(0);

let option_value_two = Some(5);

let zipped_options = Option::zip(option_value_one, option_value_two);

assert_eq!(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);

```
