Goto

A safe but not complete implementation of the goto operator.

Attention!!

At the moment, this is not a complete implementation of the goto operator.
We do not plan to violate Rust's safety standards. We provide useful and interesting macros that partially (or fully) implement the goto operator.

gpoint:

"GOTO point", allows you to return to this line later.

```rust

[macro_use]

extern crate goto;

fn main() { let data = b"1234567890"; let mut iter = data.iter(); let mut a;

gpoint!['begin:
    a = iter.next();
    match a {
        a @ Some(b'0') if a == Some(&b'9') => {
            println!("#a 0!");

            gpoint!['add:

            ];
        },
        Some(a) => {
            println!("#a {}", unsafe { std::char::from_u32_unchecked(*a as u32) });
            continue 'begin;
        },
        _ => break 'begin,
    }

];

}
