xas_reset(9)

✨ NAME ✨

xas_reset — reset an XArray operation state, bestie 💖

(it's giving "kernel API manual" energy, and yes, we're reading xas_reset(9) together, hold my iced coffee 🧊)

🦋 SYNOPSIS 🦋

void xas_reset (struct xa_state *xas );

🎀 ARGUMENTS 🎀

• xas — the XArray operation state. that's the little guy we're resetting, okurrr 💅

🌸 DESCRIPTION 🌸

okay so picture this: your xas is out here with leftover error state or walk state, and it's lowkey traumatized from whatever happened last 😭. xas_reset literally resets the error or walk state of the xas so that future walks of the array will start from the root — clean slate, main character energy, periodt ✨.

use this if you have dropped the xarray lock and want to reuse the xa_state. that's it. that's the whole vibe 🫶.

💜 CONTEXT 💜

Any context. literally any. no cap, no restrictions, we stan an unproblematic function 👑.
