3/// View into a borrowed log line
4///
5/// Unlike [`CheckedRawLogLine`](crate::raw::CheckedRawLogLine), this struct does not compute all the fields upfront,
6/// but instead provides methods to access the fields on demand.
7///
8/// This can be useful when you need to access only one or two fields from a log line.
9/// Performance gets worse if you need to access many fields;
10/// cloning the iterator becomes more expensive compared to a pre-computed struct like [`CheckedRawLogLine`](crate::raw::CheckedRawLogLine).
