Fields§

§whitespace_left: usize

The available whitespace in the left that can be consumed when centering.

§span_left: usize

The column of the beginning of left-most span.

§span_right: usize

The column of the end of right-most span.

§computed_left: usize

The beginning of the line to be displayed.

§computed_right: usize

The end of the line to be displayed.

§column_width: usize

The current width of the terminal. Uses value of DEFAULT_COLUMN_WIDTH constant by default and in tests.

§label_right: usize

The end column of a span label, including the span. Doesn’t account for labels not in the same line as the span.
