vectorio is a library for Go (aka "golang") to implement the writev(2), and in the future, readv(2) system calls. This enables a list of byte slices to be efficiently written to a file without first copying them to an intermediate buffer. Go's built-in bufio library is the standard approach to buffered I/O, but vectorio can be a replacement to achieve the same goal but without copying data.
