Struct StudyObservation 

pub struct StudyObservation { /* private fields */ }

A read-only observation of one study in the viewer’s display model.

The seam other crates use to show a study they own without handing the viewer any mutable optimizer state: build it from a hydrated StudySnapshot, rebuild it whenever the owner takes a new snapshot, and paint it with the viewer’s own charts.

Implementations

impl StudyObservation

pub fn try_new( name: impl Into<String>, source: impl Into<String>, snapshot: &StudySnapshot, ) -> Result<Self>

Builds the display model from one snapshot. name labels the study and source describes where the observation came from.

Errors

An importance computation failure.

pub fn view(&self) -> &StudyView

The observed trials.

pub fn paint_history(&self, ui: &Ui, rect: Rect)

Paints the optimization-history chart (objective values and the best-so-far curve against trial number) into rect.

pub fn paint_pareto(&self, ui: &Ui, rect: Rect)

Paints the Pareto chart (every trial’s two objective values, with the non-dominated front highlighted) into rect. A study without exactly two objectives shows a note instead.
