I have an array of bytes (u8’s) (let’s just say integers for now). The first 8 bytes is the signature of that particular sequence of bytes. I compare and check that signature (if it’s not there or doesn’t match the signature I am comparing it too) then we exit the reading operation.
The array of bytes / integers insist to communicate information through 4 byte sequences. So after reading the signature, I would collect the next 4 bytes. I take those bytes and read them, these 4 bytes indicate the length of the upcoming data segment, the next 4 bytes after that contain the data segment type. I read this to determine the type of data segment I am dealing with.
The next read operation is preformed using the length I gathered early. Let’s assume the length said 15, so after reading the data segment type, I read +15 bytes, and store them in some data structure (A Vector). After this, the next 4 bytes mark the end of the data segment. Rinse and Repeat.
