This crate allows you to combine multiple `Result` types and return either a
tuple containing all of their results, or a `Vec` of any errors which occurred.
It is useful when you want to provide an error message for all errors rather
than simply returning the first error.

Generics are used to support `Result<T, E>` for any types of `T` and `E`. The
`Ok` types of the combined results are NOT required to be the same, but all of
the `Err` types must be the same.

### [The Documentation](https://docs.rs/multi_try)

## Example

```rust
use multi_try::MultiTry;

struct A {
    b: Result<i32, MyErr>,
    c: Result<i64, MyErr>,
    d: Result<f32, MyErr>,
}

struct ValidatedA {
    b: i32,
    c: i64,
    d: f32,
}

enum MyErr {
    FailedB,
    FailedC,
    FailedD,
}

fn validate(a: A) -> Result<ValidatedA, Vec<MyErr>> {
    let (b, c, d) = a.b.and_try(a.c).and_try(a.d)?;

Ok(ValidatedA { b, c, d })
}
```
