EOS Smart Contract ABI support type _eos

In the contract, the account name, function name, structural body name length is less than or equal to 13.

Common sense: The function name does not support the decimal point, but the structure name can support underlining

The contract accounts account only supports the following characters: ". 12345abcdefghijklmnopqrstuvwxyz", which means something.

First, the type of support

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 <type>
std::string

Unsupported type, array can be substituted with vector, BOOL can be used as char instead

__int128 int128_t
size_t
signed char 
double
float

bool
array

Here is the test hello.cpp

#include <eosiolib/eosio.hpp> #include <eosiolib/print.hpp> 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<char> 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))
