EC_HTABLE...T_KEY_LEN(3)

💖 EC_HTABLE_ITER_GET_KEY_LEN 💖

okay bestie so this is a page from the Libecoli Programmer's Manual — specifically the EC_HTABLE...T_KEY_LEN(3) one (the title got squished, it's giving cryptic but we move 💅). if you've been living in the ecoli hash table section of the manual, this is the little cutie that tells you how long the key is. let's get into it 🫶

---

✨ NAME ✨

ec_htable_iter_get_key_len — Get the key length of the current element.

---

🌸 SYNOPSIS 🌸

#include <ecoli/htable.h>

size_t ec_htable_iter_get_key_len(
    const struct ec_htable_elt_ref   *iter   /* The hash table iterator. */
);

so you pull in <ecoli/htable.h> and then you call it with exactly one thing:

• iter — the hash table iterator, typed const struct ec_htable_elt_ref *. it's the little pointer to wherever you are in the table right now, no cap 🦋

and it hands you back a size_t, so it's a length, not a string. don't @ me, just read the docs.

---

💫 RETURN VALUE 💫

it gives you the key length of the current element. periodt. 👑

BUT — and this is the plot twist — if the iterator is pointing at an invalid element, you get 0 back. so like, if you're getting 0 and you're confused: check your iterator, bestie, it's probably lost 😭 the vibe check failed.
