What does this Zig snippet output?

1const std = @import("std");
2pub fn main() void {
3    const T = struct {
4        fn isEven(n: u32) bool {
5            return n % 2 == 0;
6        }
7    };
8    const arr = [_]u32{ 1, 2, 3, 4, 5 };
9    var count: u32 = 0;
10    for (arr) |v| {
11        if (T.isEven(v)) count += 1;
12    }
13    std.debug.print("{d}\n", .{count});
14}
