Brother Lian Blockchain training share go language get packed struct size

Blockchain is a complex and complex discipline that combines cryptography, consensus algorithms, intelligent contracts, and super-ledgers. Yun Jong said that the quality of the teachers in the blockchain training institutions and their perceived level in the blockchain industry were uneven, and the average consumer was not.

The go language is primarily used as a server-side development, targeting the development of "large software", suitable for many programmers to develop large-scale software together, and the development cycle of long-term support for cloud computing network services. The go language enables programmers to develop quickly, and it makes it easier for programmers to maintain and modify the software as it grows. It combines the efficiency of a traditional compiled language with the ease of use and expression of a scripting language.

Network protocol, it is possible to encounter a custom packet, corresponding to the C is

typedef struct _PACKAGEHEADER

{

int Headerlen;

int timeStamp;

Short cmd

};

To ensure single-byte alignment, you can add compilation options

#pragma pack (1)

Unfortunately, Golang inside, there is no such compilation option, the wretched reference to the cottage code as follows

Package Main

Import (

"Encoding/binary"

"FMT"

)

Type teststruct struct {

A UInt32

b int8

}

Func Main () {

var testobject teststruct

Size: = Binary. Size (Testobject)

Fmt. PRINTLN (size)

}
