Generic trait over both virtual_data and virtual_array

This provides some genral methods over csv value manipulation

Required Methods

fn new() -> Self

Create empty virtual container

fn move_row(&mut self, src_index: usize, target_index: usize) -> DcsvResult<()>

Move a given row to a target row index

fn move_column(&mut self, src_index: usize, target_index: usize) -> DcsvResult<()>

Move a given column to target column index

fn rename_column(&mut self, column_index: usize, new_name: &str) -> DcsvResult<()>

Rename a column

fn set_column(&mut self, column_index: usize, value: Value) -> DcsvResult<()>

Set values to a column

fn edit_row(
    &mut self,
    row_index: usize,
    values: &[Option<Value>]
) -> DcsvResult<()>

Edit a row

fn set_row(&mut self, row_index: usize, values: &[Value]) -> DcsvResult<()>

Set values to a row

This assumes that given values accord to column’s order.

fn get_cell(&self, x: usize, y: usize) -> Option<&Value>

get cell data by coordinate

fn set_cell(&mut self, x: usize, y: usize, value: Value) -> DcsvResult<()>

Set cell value by coordinate

fn insert_row(
    &mut self,
    row_index: usize,
    source: Option<&[Value]>
) -> DcsvResult<()>

Insert a row to given index

fn delete_row(&mut self, row_index: usize) -> bool

Delete a row with given row_index

fn insert_column(
    &mut self,
    column_index: usize,
    column_name: &str
) -> DcsvResult<()>

Insert a column with given column informations

fn delete_column(&mut self, column_index: usize) -> DcsvResult<()>

Delete a column with given column index

fn get_row_count(&self) -> usize

Get total rows count

fn get_column_count(&self) -> usize

Get total columns count

fn drop_data(&mut self)

Drop all data from virtual data

fn apply_all<F: FnMut(&mut Value)>(&mut self, f: F)

Apply closure to all values
