Lib.rs

想要数组索引不再工作吗？

只需创建一个依赖于 break_array 的crate

use break_array as _;
fn main(){
    let array=[0,1,2,3];
    assert_eq!( array[0], 0 );
}

并欣赏编译器错误

  |
6 |     assert_eq!( array[0], 0 );
  |                       ^ expected struct `break_array::MyType`, found integer

error: aborting due to previous error

For more information about this error, try `rustc --explain E0308`.

注意：如果你来自遥远的未来，你可能无法获得这个编译器错误。
