# itis

A small library for asking questions about types.

```zig

/// Example serialize function that uses `itis` to serialize ArrayList and ArrayHashMap.

pub fn serialize(writer: anytype, value: anytype) !void {

    const T = @TypeOf(value);

    if (comptime itis.anArrayList(T)) {

        try writer.writeAll("[");

        for (value.items) |item, i| {

            if (i != 0)

                try writer.writeAll(",");

            try serialize(writer, item);

        }

        return writer.writeAll("]");

    }

    if (comptime itis.anArrayHashMap(T)) {

        try writer.writeAll("{");

        for (value.keys()) |key, i| {

            const v = value.values()[i];

            if (i != 0)

                try writer.writeAll(",");

            try serialize(writer, key);

            try writer.writeAll(":");

            try serialize(writer, v);

        }

        return writer.writeAll("}");

    }

    // The rest is left as an execise for the reader

}
