Struct CellChange 

pub struct CellChange { /* private fields */ }

A highlighted change of a cell: a data cell’s, a pinned cell’s, an aggregate cell’s, or every cell of a removed row while it fades out (RowChange::Removed, with HighlightPolicy::with_removal_fade).

Implementations

impl CellChange

pub fn intensity(&self) -> f32

From 1.0 (just changed) down to the last fade step; for a removed row, down the steps of its removal fade.

pub fn change(&self) -> RowChange

What happened to the row. RowChange::Removed for every cell of a removed row while it fades out: the row is no longer in the store, the cell shows its last value.

pub fn direction(&self) -> Option<ChangeDirection>

The direction of an update, as GridRow::change_direction gave it when the store wrote the change, or as two numeric aggregates compare; None for an insert, an update without a direction (a text, mark_changed, a group’s new row count) and a removed row.

pub fn column_ix(&self) -> Option<ColumnIx>

The column of the cell: a data or pinned cell’s, an aggregate cell’s. None for a caption’s own change (a new group, a new row count), which tints the caption lane across the columns. Compare it with MyColumn::Price.ix() to paint some columns only.

pub fn fade(&self, color: Hsla) -> Hsla

color faded by the current intensity.

Trait Implementations

impl Clone for CellChange

fn clone(&self) -> CellChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CellChange

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

Formats the value using the given formatter.

impl PartialEq for CellChange

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