constexpr void remove_suffix( size_type n );
(since C++17)Moves the end of the view back by n characters.
If n > size() is true, the behavior is undefined.
(until C++26)If n > size() is true:
Constant.
[edit] Example#include <iostream> #include <string_view> int main() { char arr[] = {'a', 'b', 'c', 'd', '\0', '\0', '\0'}; std::string_view v(arr, sizeof arr); auto trim_pos = v.find('\0'); if (trim_pos != v.npos) v.remove_suffix(v.size() - trim_pos); std::cout << "Array: '" << arr << "', size=" << sizeof arr << '\n' << "View : '" << v << "', size=" << v.size() << '\n'; }
Output:
Array: 'abcd', size=7 View : 'abcd', size=4[edit] See also
