Working with structs

After seeing how slices work, we will know how to handle complex data in C and Go using structures. For this, let's see the following sections.

Structures in Go

Go structures use a technique called alignment, which consists of adding one or more bytes to data structures to make it fit into memory addresses better. Consider the following data structure:

struct {
    a string
    b bool
    c []byte
}

With 64-bit architecture calling unsafe.Sizeof on this structure, this will give us an unexpected result. What we are expecting is the following:

• 16 bytes from the string; 8 for the pointer to the first element, and 8 for the length
• 1 byte for the Boolean
• 24 for the slice; 8 for the address, 8 for...
