batch_oper provides some batch operation macro for some operations

See https://docs.rs/batch_oper/
here is just a brief introduction

Usage

Basic

batch ||
```
bop!(|| 4; == 2, > 3);
```
equivalent to
```
4 == 2 || 4 > 3
```
batch &&
```
bop!(&& 4; == 2, > 3);
```
equivalent to
```
4 == 2 && 4 > 3
```

!

bop!(|| a; == 1;!, == 2);

equivalent to

1 == a || a == 2

batch op

bop!(&& 5; > ; 2, 3, 6;!);

equivalent to

5 > 2 && 5 > 3 && 6 > 5

Set

let mut a = 1;
bop!(= a; + 1, - 2;!, * 3);

equivalent to

let mut a = 1;
a = a + 1;
a = 2 - a;
a = a * 3;

Let

bop! { let a|u8 = 1, mut b = 2 }

equivalent to

let a: u8 = 1;
let mut b = 2;

Let chain

basic

let a = Some(1);
let b = Some(2);

let _: i32 = bop!(match && Some(va) = a, Some(vb) = b => {
    1
} else {
    2
});

equivalent to

let a = Some(1);
let b = Some(2);

let _: i32 = loop {
    if let Some(va) = a {
        if let Some(vb) = b {
            break { 1 };
        }
    }
    break { 2 };
};

bool

let _: bool = bop!(bool match && Some(va) = a, Some(vb) = b => {
    1
} else {
    2
});

equivalent to

let _: bool = loop {
    if let Some(va) = a {
        if let Some(vb) = b {
            { 1 };
            break true;
        }
    }
    { 2 };
    break false;
};

!loop

let _: i32 = bop!(!loop match && Some(va) = a, Some(vb) = b => {
    1
} else {
    2
});

equivalent to

let _: i32 = if let Some(va) = a {
    if let Some(vb) = b {
        { 1 }
    } else { { 2 } }
} else  { { 2 } }

!loop bool

let _: bool = bop!(!loop bool match && Some(va) = a, Some(vb) = b => {
    1
} else {
    2
});

equivalent to

let _: bool = if let Some(va) = a {
    if let Some(vb) = b {
        { 1 }; true
    } else { { 2 }; false }
} else  { { 2 }; false }

let r = 0..5;
let c = bop!(&1, &2 => in && r);

equivalent to

let r = 0..5;
let c = r.contains(&1) && r.contains(&2);

||

let c = bop!(&1, &2 => in || r);

equivalent to

let c = r.contains(&1) || r.contains(&2);

custom funcion name

let c = bop!(has; &1, &2 => in && r);

equivalent to

let c = r.has(&1) && r.has(&2);

Using

let v = (1, 2);
let v2 = (3, 4);
using!((a, b) = v, (c, d) = v2; {
  println!("{} {} {} {}", a, b, c, d)
})

equivalent to

let v = (1, 2);
let v2 = (3, 4);
{
  let (a, b) = v;
  let (c, d) = v2;
  {
    println!("{} {} {} {}", a, b, c, d)
  }
}
