本文简要介绍rust语言中 std::string::String.as_bytes 的用法。用法pub fn as_bytes(&self) -> &[u8] 返回此 String 内容的字节切片。 此方法的逆方法是 from_utf8 。 例子 基本用法: let s = String::from("hello"); assert_eq!(&[104, 101, 108, 108, 111], s.as_bytes());...
但是实际上，对于nullptr System::String来说，一个好的c++转换应该是一个.empty() std::string()。...
typestring converts a type to its name as a constexpr std::string_view. namespace N { struct S { struct R; }; } using T = N::S::R; std::cout << typestring::name<int>; // prints int std::cout << typestring::name<N::S::R>; // prints N::S::R std::cout << type...
#include <string> #include <cassert> #include <utility> #include <type_traits> int main() { std::string mutableString = "Hello World!"; const std::string& constView = std::as_const(mutableString); assert( &constView == &mutableString ); assert( &std::as_const( mutableString ) =...
We’ll start withstd::forward_as_tuple: This takes its arguments and produces a tuple of corresponding references. int x; // produces std::tuple<int&, std::string&&> std::forward_as_tuple(x, std::string(L"hello")); Note that this potentially contains a tuple of rvalue references, ...
void to_string(string & result,const T& t) { ostringstream oss;//创建一个流 oss<<t;//把值传递如流中 result=oss.str();//获取转换后的字符转并将其写入result } 1. 2. 3. 4. 5. 6. 7. 这样,你就可以轻松地将多种数值转换成字符串了: ...
