What does this Zig snippet output?

1const std = @import("std");
2pub fn main() void {
3    const result = outer: {
4        var i: u32 = 0;
5        while (i < 10) : (i += 1) {
6            if (i * i > 50) break :outer i;
7        }
8        break :outer 0;
9    };
10    std.debug.print("{d}\n", .{result});
11}
