constexpr void remove_prefix(size_type n); |
(library fundamentals TS) | |
Moves the start of the view forward by n characters.
The behavior is undefined if n > size().
Parameters
| n | - | number of characters to remove from the start of the view |
Return value
(none)
Complexity
Constant.
Example
Run this code
#include <iostream> #include <experimental/string_view> int main() { std::string str = " trim me"; std::experimental::string_view v = str; v.remove_prefix(std::min(v.find_first_not_of(" "), v.size())); std::cout << "String: '" << str << "'\n" << "View : '" << v << "'\n"; }
Output:
String: ' trim me' View : 'trim me'
