Each has methods that help improve -// the encoding/decoding performance of some binary -// protocols. -// -// The `fwd.Writer` and `fwd.Reader` type provide similar -// functionality to their counterparts in `bufio`, plus -// a few extra utility methods that simplify read-ahead -// and write-ahead. I wrote this package to improve serialization -// performance for http://github.com/tinylib/msgp, -// where it provided about a 2x speedup over `bufio` for certain -// workloads. However, care must be taken to understand the semantics of the -// extra methods provided by this package, as they allow -// the user to access and manipulate the buffer memory -// directly. -// -// The extra methods for `fwd.Reader` are `Peek`, `Skip` -// and `Next`. `(*fwd.Reader).Peek`, unlike `(*bufio.Reader).Peek`, -// will re-allocate the read buffer in order to accommodate arbitrarily -// large read-ahead. `(*fwd.Reader).Skip` skips the next `n` bytes -// in the stream, and uses the `io.Seeker` interface if the underlying -// stream implements it. `(*fwd.Reader).Next` returns a slice pointing -// to the next `n` bytes in the read buffer (like `Peek`), but also -// increments the read position. This allows users to process streams -// in arbitrary block sizes without having to manage appropriately-sized -// slices. Additionally, obviating the need to copy the data from the -// buffer to another location in memory can improve performance dramatically -// in CPU-bound applications. -// -// `fwd.Writer` only has one extra method, which is `(*fwd.Writer).Next`, which -// returns a slice pointing to the next `n` bytes of the writer, and increments -// the write position by the length of the returned slice. This allows users -// to write directly to the end of the buffer. -package fwd - -import "io" - -const ( - // DefaultReaderSize is the default size of the read buffer - DefaultReaderSize = 2048 - - // minimum read buffer; straight from bufio - minReaderSize = 16 -) - -// NewReader returns a new *Reader that reads from 'r' -func NewReader(r io.Reader) *Reader { - return NewReaderSize(r, DefaultReaderSize) -} - -// NewReaderSize returns a new *Reader that -// reads from 'r' and has a buffer size 'n'. -func NewReaderSize(r io.Reader, n int) *Reader { - buf := make([]byte, 0, max(n, minReaderSize)) - return NewReaderBuf(r, buf) -} - -// NewReaderBuf returns a new *Reader that -// reads from 'r' and uses 'buf' as a buffer. -// 'buf' is not used when has smaller capacity than 16, -// custom buffer is allocated instead. -func NewReaderBuf(r io.Reader, buf []byte) *Reader { - if cap(buf) < minReaderSize { - buf = make([]byte, 0, minReaderSize) - } - buf = buf[:0] - rd := &Reader{ - r: r, - data: buf, - } - if s, ok := r.(io.Seeker); ok { - rd.rs = s - } - return rd -} - -// Reader is a buffered look-ahead reader -type Reader struct { - r io.Reader // underlying reader - - // data[n:len(data)] is buffered data; data[len(data):cap(data)] is free buffer space - data []byte // data - n int // read offset - state error // last read error - - // if the reader past to NewReader was - // also an io.Seeker, this is non-nil - rs io.Seeker -} - -// Reset resets the underlying reader -// and the read buffer. -func (r *Reader) Reset(rd io.Reader) { - r.r = rd - r.data = r.data[0:0] - r.n = 0 - r.state = nil - if s, ok := rd.(io.Seeker); ok { - r.rs = s - } else { - r.rs = nil - } -} - -// more() does one read on the underlying reader -func (r *Reader) more() { - // move data backwards so that - // the read offset is 0; this way - // we can supply the maximum number of - // bytes to the reader - if r.n != 0 { - if r.n < len(r.data) { - r.data = r.data[:copy(r.data[0:], r.data[r.n:])] - } else { - r.data = r.data[:0] - } - r.n = 0 - } - var a int - a, r.state = r.r.Read(r.data[len(r.data):cap(r.data)]) - if a == 0 && r.state == nil { - r.state = io.ErrNoProgress - return - } else if a > 0 && r.state == io.EOF { - // discard the io.EOF if we read more than 0 bytes. - // the next call to Read should return io.EOF again. - r.state = nil - } - r.data = r.data[:len(r.data)+a] -} - -// pop error -func (r *Reader) err() (e error) { - e, r.state = r.state, nil - return -} - -// pop error; EOF -> io.ErrUnexpectedEOF -func (r *Reader) noEOF() (e error) { - e, r.state = r.state, nil - if e == io.EOF { - e = io.ErrUnexpectedEOF - } - return -} - -// buffered bytes -func (r *Reader) buffered() int { return len(r.data) - r.n } - -// Buffered returns the number of bytes currently in the buffer -func (r *Reader) Buffered() int { return len(r.data) - r.n } - -// BufferSize returns the total size of the buffer -func (r *Reader) BufferSize() int { return cap(r.data) } - -// Peek returns the next 'n' buffered bytes, -// reading from the underlying reader if necessary. -// It will only return a slice shorter than 'n' bytes -// if it also returns an error.
