Struct ColumnOrder 

pub struct ColumnOrder { /* private fields */ }

Manages the order and visibility of columns in a table.

Implementations

impl ColumnOrder

pub fn new(total_columns: usize) -> Self

Creates a new ColumnOrder with default ordering (all columns visible in natural order)

pub fn get_order(&self) -> &[usize]

Returns the current column order as a slice

pub fn total_columns(&self) -> usize

Returns the total number of columns

pub fn swap(&mut self, col_a: usize, col_b: usize)

Swaps two columns in the display order. If either column is hidden or out of bounds, this is a no-op (saturating behavior).

pub fn hide_column(&mut self, col: usize)

Hides a column by removing it from the display order. If the column is already hidden or out of bounds, this is a no-op.

pub fn show_column(&mut self, col: usize, at_index: Option<usize>)

Shows a column by inserting it into the display order. If at_index is None, appends to the end. If at_index is Some(idx), inserts at that position (saturated to valid range). If the column is already visible or out of bounds, this is a no-op.

pub fn move_to(&mut self, col: usize, new_index: usize)

Moves a column to a specific position in the display order (0-indexed). The position is saturated to the valid range. If the column is hidden or out of bounds, this is a no-op.

pub fn move_forward(&mut self, col: usize)

Moves a column one position forward (towards index 0) in the display order. If the column is already first or hidden, this is a no-op.

pub fn move_backward(&mut self, col: usize)

Moves a column one position backward (towards the end) in the display order. If the column is already last or hidden, this is a no-op.

pub fn is_visible(&self, col: usize) -> bool

Checks if a column is currently visible

pub fn position(&self, col: usize) -> Option<usize>

Returns the display position of a column (0-indexed), or None if hidden

pub fn reset(&mut self)

Resets the column order to the default state (all columns visible in natural order)

Trait Implementations

impl Clone for ColumnOrder

fn clone(&self) -> ColumnOrder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnOrder

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

Formats the value using the given formatter.

impl PartialEq for ColumnOrder

fn eq(&self, other: &ColumnOrder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
