在Zig中如何在编译时连接两个字符串？

const std = @import("std");

pub fn main() !void {
    const allocator = std.heap.page_allocator;
    var b = std.Buffer.init(allocator);
    
    const str1 = "Hello, ";
    const str2 = "world!";
    
    try b.append(str1);
    try b.append(str2);
    
    const result = b.toOwnedSlice();
    std.debug.print("Concatenated string: {}\n", .{result});
}
