pub struct PagerState {
    pub line_numbers: LineNumbers,
    pub upper_mark: usize,

    pub rows: usize,
    pub cols: usize,
    pub prefix_num: String,
    /* private fields */
}

Holds all information and configuration about the pager during its un time.

This type is exposed so that end-applications can implement the InputClassifier trait which requires the PagerState to be passed as a parameter

rows: usize
