EOS 智能合约转ABI 支持类型

合约中，账户名，函数名，结构体名长度都要小于等于13。

常识：函数名不支持小数点，结构体名却可以支持下划线

合约账户account只支持下面字符：".12345abcdefghijklmnopqrstuvwxyz"，有点意思

先说一下，支持的类型

unsigned __int128 uint128_t
unsigned long long uint64_t
unsigned long uint32_t
unsigned short  uint16_t
unsigned char uint8_t
long long int64_t
long int32_t
short int16_t
char int8_t
std::vector
std::string

不支持的类型，数组可以用vector代替，bool可以用char代替

__int128 int128_t
size_t
signed char 
double
float

bool
数组

下面是测试的hello.cpp

#include   
#include   
using namespace eosio;  
  
class hello : public eosio::contract {  
  public:  
      using contract::contract;  
  
      /// @abi action   
      void hi ( account_name user ) {  
         print( "Hello, ", name{user} );  
      }  
      //@abi table test i64
      struct test
      {

      	unsigned __int128	uint128_1;
      	uint128_t 			uint128_2;
      	
      	unsigned long long  uint64_1;
      	uint64_t            uint64_2;

		unsigned long       uint32_1;
		uint32_t        	uint32_2;

		unsigned short      uint16_1;
		uint16_t          	uint16_2;
		
		unsigned char       uint8_1;
		uint8_t 			uint8_2;

		long long 			int64_1;
		int64_t 			int64_2;
      	
      	long 				int32_1;
      	int32_t 			int32_2;
      	
      	short 				int16_1;
      	int16_t 			int16_2;
      	
      	char 				int8_1;
      	int8_t 				int8_2;

      	std::vector vec;
      	std::string str;

      	// __int128          int128;
      	// int128_t          int128_2;
      	// char s[10];
      	// signed char s_char;
      	//bool bl;
      	//double dl;
      	//float ft;
      	// size_t st;
      };
};  
  
EOSIO_ABI( hello, (hi) )
