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

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.
