Describes a mutation to a chart’s series or point data. Emitted by ChartModel<T> automatically.

Variants

SeriesInserted

A series was inserted at the given index.

Fields

index: usize

series: SeriesId

SeriesRemoved

A series (and all of its points) was removed.

Fields

series: SeriesId

SeriesMoved

A series was moved to a new position among its siblings.

Fields

series: SeriesId

from: usize

to: usize

SeriesRenamed

A series’ display name changed.

Fields

series: SeriesId

SeriesColorChanged

A series’ explicit color changed (set or cleared). The only variant that bumps crate::ChartModel::style_version rather than crate::ChartModel::structure_version.

Fields

series: SeriesId

SeriesPatternChanged

A series’ explicit SeriesPattern changed (set or cleared). Paint-only, like SeriesColorChanged: it bumps crate::ChartModel::style_version, not structure_version.

Fields

series: SeriesId

SeriesVisibilityChanged

A series’ visibility flag changed.

Fields

series: SeriesId

PointsInserted

Points were inserted; range holds the indices of the newly inserted points within series.

Fields

series: SeriesId

range: Range<usize>

PointsRemoved

Points were removed; range holds the indices they occupied before removal within series.

Fields

series: SeriesId

range: Range<usize>

PointUpdated

A single point’s data changed in place without any structural shift.

Fields

series: SeriesId

index: usize

SeriesDataReplaced

A series’ entire point list was replaced; consumers must discard cached state for that series and rebuild it.

Fields

series: SeriesId

Reset

The entire chart was replaced. Consumers should discard all state and rebuild.

Trait Implementations

impl Clone for ChartChange

fn clone(&self) -> ChartChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChartChange

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

Formats the value using the given formatter.

impl Eq for ChartChange

impl PartialEq for ChartChange

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