Learn Zig Series (#17) - Packed Structs and Bit Manipulation What will I learn You will learn how packed structs lay out fields with exact bit widths; the difference between packed struct and regular struct memory layout; bitwise operations in Zig: AND, OR, XOR, shifts, and where to use them; reading and writing individual bits and bit ranges using packed structs; @bitCast for reinterpreting bit patterns between types; endianness considerations with std.mem.nativeToBig and friends; real-world example: parsing a DNS header with packed structs; common packed struct pitfalls and how to avoid them. Requirements A working modern computer running macOS, Windows or Ubuntu; An installed Zig 0.14+ distribution (download from ziglang.org); The ambition to learn Zig programming.
