here is just a brief introduction
|| rust
bop!(|| 4; == 2, > 3);
equivalent to
rust
4 == 2 || 4 > 3
&& rust
bop!(&& 4; == 2, > 3);
equivalent to
rust
4 == 2 && 4 > 3
!
rust
bop!(|| a; == 1;!, == 2);
equivalent to
rust
1 == a || a == 2
rust
bop!(&& 5; > ; 2, 3, 6;!);
equivalent to
rust
5 > 2 && 5 > 3 && 6 > 5
rust
let mut a = 1;
bop!(= a; + 1, - 2;!, * 3);
equivalent to
rust
let mut a = 1;
a = a + 1;
a = 2 - a;
a = a * 3;
rust
bop! { let a|u8 = 1, mut b = 2 }
equivalent to
rust
let a: u8 = 1;
let mut b = 2;
Let chain
let _: i32 = bop!(match && Some(va) = a, Some(vb) = b => {
1
} else {
2
});
*equivalent to*
rust
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
rust
let _: bool = bop!(bool match && Some(va) = a, Some(vb) = b => {
1
} else {
2
});
equivalent to
rust
let _: bool = loop {
if let Some(va) = a {
if let Some(vb) = b {
{ 1 };
break true;
}
}
{ 2 };
break false;
};
!loop
rust
let _: i32 = bop!(!loop match && Some(va) = a, Some(vb) = b => {
1
} else {
2
});
equivalent to
rust
let _: i32 = if let Some(va) = a {
if let Some(vb) = b {
{ 1 }
} else { { 2 } }
} else { { 2 } }
!loop bool
rust
let _: bool = bop!(!loop bool match && Some(va) = a, Some(vb) = b => {
1
} else {
2
});
equivalent to
rust
let _: bool = if let Some(va) = a {
if let Some(vb) = b {
{ 1 }; true
} else { { 2 }; false }
} else { { 2 }; false }
rust
let r = 0..5;
let c = bop!(&1, &2 => in && r);
equivalent to
rust
let r = 0..5;
let c = r.contains(&1) && r.contains(&2);
||
rust
let c = bop!(&1, &2 => in || r);
equivalent to
rust
let c = r.contains(&1) || r.contains(&2);
rust
let c = bop!(has; &1, &2 => in && r);
equivalent to
rust
let c = r.has(&1) && r.has(&2);
Using
rust
let v = (1, 2);
let v2 = (3, 4);
using!((a, b) = v, (c, d) = v2; {
println!("{} {} {} {}", a, b, c, d)
})
equivalent to
rust
let v = (1, 2);
let v2 = (3, 4);
{
let (a, b) = v;
let (c, d) = v2;
{
println!("{} {} {} {}", a, b, c, d)
}
}
