2.4. Padding

Attention

This section is subject to change if Padding is implemented.

In binary file formats, padding is often used to align data to certain byte boundaries. Caterpillar provides a way to handle padding within structs. However, it is important to note that caterpillar doesn’t store any data associated with the padding itself unless explicitly defined. If you need to retain or manipulate the padding content, you can use the Bytes or Memory field types.

If you want to apply padding to a struct, you can simply specify the padding length using the padding keyword. This is useful when you need to ensure that certain fields are aligned or when the structure requires reserved spaces.

>>> field = padding[10] # greedy or dynamic size
