BSON_WRITER_ROLLBACK(3)

πŸ’… BSON_WRITER_ROLLBACK πŸ’…

okay so bestie, welcome to the libbson corner of the manual β€” this one's about BSON_WRITER_ROLLBACK(3) and honestly it's giving "undo button for your memory region" energy ✨


πŸŽ€ SYNOPSIS πŸŽ€

void
bson_writer_rollback (bson_writer_t *writer);

literally the whole signature, no cap 🫢


🌸 PARAMETERS 🌸

  • writer β€” a bson_writer_t. that's it, that's the whole vibe πŸ’–

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so here's the tea β˜• β€” bson_writer_rollback() aborts the appending of the current bson_t to the memory region that writer is managing. like, nope, we're not doing that anymore, take it back πŸ’…

and why would you ever want that? because it's genuinely useful when you've detected that you went past a particular memory limit πŸ‘€ β€” like oops, too much, my bad, rewind.

for example (and this is a real one, not me making stuff up): MongoDB has 48MB message limits. so yeah. if you blow past that, rollback is your bestie 🫢

fr fr keep this one in your back pocket β€” hitting a memory limit is not the moment to be dramatic, it's the moment to call rollback 😌
