[![license](http://img.shields.io/crates/l/moreops.png)](https://crates.io/crates/moreops)

[![version](http://img.shields.io/crates/v/moreops.png)](https://crates.io/crates/moreops)

A set of useful simple additional methods

Usage:

```toml

[dependencies]

moreops = "*"

```

Examples:

```rust

use moreops::*;

// Simple wrapping into Option

let some_num = 123.some();

let none_num = none::();

// Simple wrapping into Result

let ok = 123.ok();

let err = "Error!".to_owned().err();

// If-like operations with Option

let x = 42;

let answer = (x % 2 == 0).option("even").unwrap_or("odd");

// Tap into some result (like `<|` and `|>` operators from Scalaz)

fn f() -> i32 {

    123

}

assert_eq!(f().tap(|x| println!("{:?}", x)), 123);

assert_eq!(f().pipe(|x| x * 2), 246);

// Swap result

assert_eq!(123.ok().swap(), 123.err());

assert_eq!(123.ok().swap().swap(), 123.ok());

// Apply functions to tuples of args directly

let x = (2, 3, 4).apply(|a, b, c| a * b * c);

assert_eq!(x, 24);

// Use twice() to build map

let map = (1..10).map(twice).collect::<::std::collections::BTreeMap<_, _>>();

```
