Overview

Package binary implements simple translation between numbers and byte sequences and encoding and decoding of varints.

Numbers are translated by reading and writing fixed-size values. A fixed-size value is either a fixed-size arithmetic type (int8, uint8, int16, float32, complex64, ...) or an array or struct containing only fixed-size values.

The varint functions encode and decode single integer values using a variable-length encoding; smaller values require fewer bytes. For a specification, see http://code.google.com/apis/protocolbuffers/docs/encoding.html.

This package favors simplicity over efficiency. Clients that require high-performance serialization, especially for large data structures, should look at more advanced solutions such as the encoding/gob package or protocol buffers.

Functions

func PidExists 

func PidExists(pid int32) (bool, error)

func Pids 

func Pids() ([]int32, error)

func Read 

func Read(r io.Reader, order ByteOrder, data interface{}) error

Read reads structured binary data from r into data. Data must be a pointer to a fixed-size value or a slice of fixed-size values. Bytes read from r are decoded using the specified byte order and written to successive fields of the data. When reading into structs, the field data for fields with blank (_) field names is skipped; i.e., blank field names may be used for padding. When reading into a struct, all non-blank fields must be exported.

func Size 

func Size(v interface{}) int

Size returns how many bytes Write would generate to encode the value v, which must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. If v is neither of these, Size returns -1.

func Write 

func Write(w io.Writer, order ByteOrder, data interface{}) error

Write writes the binary representation of data into w. Data must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. Bytes written to w are encoded using the specified byte order and read from successive fields of the data. When writing structs, zero values are written for fields with blank (_) field names.
