🦋 ARGUMENTS 🦋

  • dev — the Device you're iterating resources from. like, this is the whole vibe-check starting point, k? 💖
  • release — you're looking for resources that are associated with this release function, so it's basically the matching key for the release side of things 🔑
  • match — the Match function — and listen, she's optional, no cap 🙈
  • match_data — the Data that gets handed to that match function. feed her well 🍓
  • fn — the Function that gets called for each matched resource. this is the callback that does the actual slaying 🔥
  • data — Data for fn — and yes it's literally the 3rd parameter of fn, so it all lines up, iykyk ⭐
