This post details the design and implementation of automatic buffer management using io_uring's buffer rings feature. The system sets up a shared pool of kernel-provided buffers for multishot read/recv operations across multiple concurrent connections, with auto-refill logic to maintain available buffer space. To minimize data copying, read data is tracked as segmented linked lists of buffer references, only copied once when converted to Ruby strings. Segment structs are recycled via free lists to minimize allocations. The resulting API (UM::IO) exposes simple sequential methods like read, read_line, and read_to_delim, hiding all buffering complexity. Example implementations for HTTP/1.1 parsing and Redis RESP protocol are shown. Future plans include IPv6, more protocol implementations, and integration with Rails, Hanami, and Sidekiq. ## Full article daily.dev links to this article rather than hosting it.
