+# fwd
+    import "github.com/philhofer/fwd"
+
+The `fwd` package provides a buffered reader
+and writer. 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 <a href="http://github.com/tinylib/msgp">http://github.com/tinylib/msgp</a>,
+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.
+
+
+
+
+## Constants
+``` go
+const (
+    // DefaultReaderSize is the default size of the read buffer
+    DefaultReaderSize = 2048
+)
+```
+``` go
+const (
+    // DefaultWriterSize is the
+    // default write buffer size.
+    DefaultWriterSize = 2048
+)
+```
+
+
+
+## type Reader
+``` go
+type Reader struct {
+    // contains filtered or unexported fields
+}
+```
+Reader is a buffered look-ahead reader
+
+
+
+
+
+
+
+
+
+### func NewReader
+``` go
+func NewReader(r io.Reader) *Reader
+```
+NewReader returns a new *Reader that reads from 'r'
+
+
+### func NewReaderSize
+``` go
+func NewReaderSize(r io.Reader, n int) *Reader
+```
+NewReaderSize returns a new *Reader that
+reads from 'r' and has a buffer size 'n'
+
+
+
+
+### func (\*Reader) BufferSize
+``` go
+func (r *Reader) BufferSize() int
+```
+BufferSize returns the total size of the buffer
+
+
+
+### func (\*Reader) Buffered
+``` go
+func (r *Reader) Buffered() int
+```
+Buffered returns the number of bytes currently in the buffer
+
+
+
+### func (\*Reader) Next
+``` go
+func (r *Reader) Next(n int) ([]byte, error)
+```
+Next returns the next 'n' bytes in the stream.
+Unlike Peek, Next advances the reader position.
+The returned bytes point to the same
+data as the buffer, so the slice is
+only valid until the next reader method call.
+An EOF is considered an unexpected error.
+If an the returned slice is less than the
+length asked for, an error will be returned,
+and the reader position will not be incremented.
+
+
+
+### func (\*Reader) Peek
+``` go
+func (r *Reader) Peek(n int) ([]byte, error)
+```
+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. Peek does not advance
+the reader. EOF errors are *not* returned as
+io.ErrUnexpectedEOF.
+
+
+
+### func (\*Reader) Read
+``` go
+func (r *Reader) Read(b []byte) (int, error)
+```
+Read implements `io.Reader`
+
+
+
+### func (\*Reader) ReadByte
+``` go
+func (r *Reader) ReadByte() (byte, error)
+```
+ReadByte implements `io.ByteReader`
+
+
+
+### func (\*Reader) ReadFull
+``` go
+func (r *Reader) ReadFull(b []byte) (int, error)
+```
+ReadFull attempts to read len(b) bytes into
+'b'. It returns the number of bytes read into
+'b', and an error if it does not return len(b).
+EOF is considered an unexpected error.
+
+
+
+### func (\*Reader) Reset
+``` go
+func (r *Reader) Reset(rd io.Reader)
+```
+Reset resets the underlying reader
+and the read buffer.
+
+
+
+### func (\*Reader) Skip
+``` go
+func (r *Reader) Skip(n int) (int, error)
+```
+Skip moves the reader forward 'n' bytes.
+Returns the number of bytes skipped and any
+errors encountered. It is analogous to Seek(n, 1).
+If the underlying reader implements io.Seeker, then
+that method will be used to skip forward.
+
+If the reader encounters
+an EOF before skipping 'n' bytes, it
+returns io.ErrUnexpectedEOF. If the
+underlying reader implements io.Seeker, then
+those rules apply instead. (Many implementations
+will not return `io.EOF` until the next call
+to Read.)
+
+
+
+### func (\*Reader) WriteTo
+``` go
+func (r *Reader) WriteTo(w io.Writer) (int64, error)
+```
+WriteTo implements `io.WriterTo`
+
+
+
+## type Writer
+``` go
+type Writer struct {
+    // contains filtered or unexported fields
+}
+```
+Writer is a buffered writer
+
+
+
+
+
+
+
+
+
+### func NewWriter
+``` go
+func NewWriter(w io.Writer) *Writer
+```
+NewWriter returns a new writer
+that writes to 'w' and has a buffer
+that is `DefaultWriterSize` bytes.
+
+
+### func NewWriterSize
+``` go
+func NewWriterSize(w io.Writer, size int) *Writer
+```
+NewWriterSize returns a new writer
+that writes to 'w' and has a buffer
+that is 'size' bytes.
+
+
+
+
+### func (\*Writer) BufferSize
+``` go
+func (w *Writer) BufferSize() int
+```
+BufferSize returns the maximum size of the buffer.
+
+
+
+### func (\*Writer) Buffered
+``` go
+func (w *Writer) Buffered() int
+```
+Buffered returns the number of buffered bytes
+in the reader.
+
+
+
+### func (\*Writer) Flush
+``` go
+func (w *Writer) Flush() error
+```
+Flush flushes any buffered bytes
+to the underlying writer.
+
+
+
+### func (\*Writer) Next
+``` go
+func (w *Writer) Next(n int) ([]byte, error)
+```
+Next returns the next 'n' free bytes
+in the write buffer, flushing the writer
+as necessary. Next will return `io.ErrShortBuffer`
+if 'n' is greater than the size of the write buffer.
+Calls to 'next' increment the write position by
+the size of the returned buffer.
+
+
+
+### func (\*Writer) ReadFrom
+``` go
+func (w *Writer) ReadFrom(r io.Reader) (int64, error)
+```
+ReadFrom implements `io.ReaderFrom`
+
+
+
+### func (\*Writer) Write
+``` go
+func (w *Writer) Write(p []byte) (int, error)
+```
+Write implements `io.Writer`
+
+
+
+### func (\*Writer) WriteByte
+``` go
+func (w *Writer) WriteByte(b byte) error
+```
+WriteByte implements `io.ByteWriter`
+
+
+
+### func (\*Writer) WriteString
+``` go
+func (w *Writer) WriteString(s string) (int, error)
+```
+WriteString is analogous to Write, but it takes a string.
