1/// A caller's read loop switches on this result to handle a line, read more input, or stop. The2/// union holds the result of one poll: a whole line, a request for more input, or the end of input.3/// The client's read loop and another program's server loop both switch on it.4pub const Poll = union(enum) {5    /// Carries one line without its newline, as a slice of the reader's buffer. The slice also6    /// holds the last bytes of the input when it ends without a newline. The reader splits at `\n`7    /// alone and keeps a carriage return before it. The slice remains valid until the next call to8    /// `writable`, which moves the unread bytes, or to `deinit`.9    line: []const u8,10    /// Signals that no whole line is buffered yet.
