Trait for accessing the table-data by the FTable.

This trait is suitable if the underlying data is an iterator. It uses internal iteration which allows much more leeway with borrowing & lifetimes.

Required Methods

fn rows(&self) -> Option<usize>

Returns the number of rows, if known.

If they are not known, all items will be iterated to calculate things as the length of the table. Which will be slower if you have many items.

fn nth(&mut self, n: usize) -> bool

Skips to the nth item, returns true if such an item exists. nth(0) == next()

fn render_cell(&self, column: usize, area: Rect, buf: &mut Buffer)

Render the cell for the current line.

Provided Methods

fn header(&self) -> Option<Row<'a>>

Header can be obtained from here. Alternative to setting on FTable.

fn footer(&self) -> Option<Row<'a>>

Footer can be obtained from here. Alternative to setting on FTable.

fn next(&mut self) -> bool

Reads the next item, returns true if such an item exists.

fn row_height(&self) -> u16

Row height for the current item.

fn row_style(&self) -> Option<Style>

Row style for the current line.

fn widths(&self) -> Vec<Constraint>

Column constraints.
