STRUCT NAND_OP_PARSER_PATTERN_ELEM(9)

💅 struct nand_op_parser_pattern_elem(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the ./include/linux/mtd/rawnand.h universe and you meet this little guy — struct nand_op_parser_pattern_elem, aka one single element of a pattern ✨ that's literally the NAME, no cap.

She's a tiny struct but she's main character energy in the NAND op parser, so let's get into it 🫶

✨ SYNOPSIS ✨

like, here's her whole gorgeous shape, verbatim, don't touch:

struct nand_op_parser_pattern_elem {
    enum nand_op_instr_type type;
    bool optional;
    union {
      struct nand_op_parser_addr_constraints addr;
      struct nand_op_parser_data_constraints data;
    } ctx;
 };

🎀 MEMBERS 🎀

• type — the instruction type 💫 (the original says "instructuction type", and honestly? iconic typo, we keep the meaning: it's the type of instruction).
• optional — a bool that tells you whether this element of the pattern is optional or mandatory. choose your own adventure vibes 🌸
• ctx — the union holding either the address constraint or the data constraint. she contains multitudes 💜
• ctx.addr — the address constraint, which is about the number of cycles ⏱️
• ctx.data — the data constraint, which is about the data length 📏

ngl the union is doing a lot of work here — addr and data share the same ctx spot, so it's one or the other, not both. that's just what a union is, bestie, no drama 💀
