=== from_chars_result
The `from_chars_result` structure contains the result of a `from_chars` call, where the `ptr` member points to the first character that was
not consumed during parsing and `ec` is `from_chars_error::none`, if parsing succeeded, otherwise the error code returned by the parser.
```
constexpr explicit operator bool() const noexcept;
```
Returns: :: `this->ec == from_chars_error::none`.
