multi_try

This crate allows combining multiple Result types, and returning 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 error types must be the same.

Example

```rust struct A { b: Result, c: Result, d: Result, }

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

enum MyErr { FailedB, FailedC, FailedD, }

fn validate(a: A) -> Result> { let (b, c, d) = multi_try::and( a.b, a.c ) .and(a.d)?;

Ok(ValidatedA { b, c, d })

} ```

Nightly Rust Required

For now multi_try requires nightly Rust, due to usage of the Try trait.
