The representaion of data, rows and columns of a Grid.

Required Methods

fn count_rows(&self) -> usize

Returns amount of rows on a grid.

fn count_columns(&self) -> usize

Returns amount of columns on a grid.

fn get_text(&self, pos: Position) -> &str

Returns a text of a cell by an index.

fn get_line(&self, pos: Position, i: usize) -> &str

Returns a line of a text of a cell by an index.

fn count_lines(&self, pos: Position) -> usize

Returns an amount of lines of a text of a cell by an index.

fn get_width<W>(&self, pos: Position, width_ctrl: W) -> usize

where W: WidthFunc,

Returns a width of a text of a cell by an index.

fn get_line_width<W>(&self, pos: Position, i: usize, width_ctrl: W) -> usize

where W: WidthFunc,

Returns a width of line of a text of a cell by an index.

fn fmt_text_prefix(&self, f: &mut Formatter<'_>, pos: Position) -> Result

Prints a prefix of a text of a cell by an index.

Maybe be usefull in order to emit ANSI sequences.

fn fmt_text_suffix(&self, f: &mut Formatter<'_>, pos: Position) -> Result

Prints a suffix of a text of a cell by an index.

Maybe be usefull in order to emit ANSI sequences.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
