How to use std.json to parse an array of arrays of strings and numbers. Specifically the “cycles” attribute of the JSON below.

If it cannot be parsed, how can I make it ignore the “cycles” attribute?

const Data = []struct {
        name: []u8,
        initial: struct {
            pc: u16,
            sp: u16,
            a: u8,
            b: u8,
            c: u8,
            d: u8,
            e: u8,
            f: u8,
            h: u8,
            l: u8,
            ime: u32,
            ie: u32,
            ram: [][]u16,
        },
        final: struct {
            pc: u16,
            sp: u16,
            a: u8,
            b: u8,
            c: u8,
            d: u8,
            e: u8,
            f: u8,
            h: u8,
            l: u8,
            ime: u32,
            ram: [][]u16,
        },
        cycles: [][][]u8,
    };

const result = try std.json.parseFromSlice(Data, std.testing.allocator, data, .{});

                ]
            ]
        },
        "cycles": [
            [
                19935,
                0,

            ]
        ]
    },

I think this would work:

cycles: [][]std.json.Value,

Then switch on the union.
