Struct ExpandingState 

pub struct ExpandingState { /* private fields */ }

Complete expanding state for the table.

Tracks which rows are expanded and provides configuration for automatic expansion behavior.

Implementations

impl ExpandingState

pub fn new() -> ExpandingState

Creates a new empty expanding state.

Returns

• ExpandingState: A new expanding state with no rows expanded.

pub fn all_expanded() -> ExpandingState

Creates an expanding state with all rows expanded.

Returns

• ExpandingState: A new expanding state with expand-all enabled.

pub fn with_auto_expand_parents(self, auto: bool) -> ExpandingState

Sets whether to auto-expand parent rows.

Parameters

• auto: Whether parent rows should be auto-expanded.

Returns

• Self: The modified expanding state.

pub fn with_auto_expand_depth(self, depth: usize) -> ExpandingState

Sets the maximum auto-expansion depth.

Parameters

• depth: The maximum depth level for auto-expansion.

Returns

• Self: The modified expanding state.

pub fn is_expanded(&self, row_id: &DataTableRowId) -> bool

Returns whether the given row is expanded.

Parameters

• row_id: The row identifier to check.

Returns

• bool: Whether the row is expanded.

pub fn expanded_count(&self) -> usize

Returns the number of expanded rows.

Returns

• usize: The count of individually expanded rows.

pub fn has_expanded(&self) -> bool

Returns whether any rows are explicitly expanded.

Returns

• bool: Whether expand-all is set or individual rows are expanded.

pub fn expanded_ids(&self) -> impl Iterator<Item = &DataTableRowId>

Returns the expanded row IDs.

Returns

• impl Iterator<Item = &DataTableRowId>: An iterator over expanded row IDs.

pub fn is_expand_all(&self) -> bool

Returns whether all rows are expanded by default.

Returns

• bool: Whether expand-all mode is active.

pub fn expand(&mut self, row_id: DataTableRowId)

Expands a row.

Parameters

• row_id: The row identifier to expand.

pub fn collapse(&mut self, row_id: &DataTableRowId)

Collapses a row.

Parameters

• row_id: The row identifier to collapse.

pub fn toggle(&mut self, row_id: DataTableRowId)

Toggles the expansion state of a row.

Parameters

• row_id: The row identifier to toggle.

pub fn expand_many(&mut self, row_ids: impl IntoIterator<Item = DataTableRowId>)

Expands multiple rows.

Parameters

• row_ids: The row identifiers to expand.

pub fn collapse_many( &mut self, row_ids: impl IntoIterator<Item = DataTableRowId>, )

Collapses multiple rows.

Parameters

• row_ids: The row identifiers to collapse.

pub fn expand_all(&mut self)

Expands all rows.

pub fn collapse_all(&mut self)

Collapses all rows.

pub fn toggle_all(&mut self)

Toggles expand all state.

pub fn reset(&mut self)

Resets to initial state.

pub fn should_auto_expand(&self, depth: usize) -> bool

Checks if a row at the given depth should be auto-expanded.

Parameters

• depth: The nesting depth level.

Returns

• bool: Whether the row should be auto-expanded.

Trait Implementations

impl Clone for ExpandingState

fn clone(&self) -> ExpandingState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpandingState

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

Formats the value using the given formatter.

impl Default for ExpandingState

fn default() -> ExpandingState

Returns the “default value” for a type.

impl PartialEq for ExpandingState

fn eq(&self, other: &ExpandingState) -> 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.
