Function: barIdFromDataset()

barIdFromDataset(value): BarId | undefined

Defined in: model/ids.ts:33

Call: barIdFromDataset(bar.dataset['barId']) — the DOM→brand trust boundary for a .fg-bar node's data-bar-id attribute (render/dom/index.ts is what writes it). undefined in, undefined out, so a caller keeps its own "no bar hit" branch instead of taking one here.

Parameters​

value​

string | undefined

Returns​

BarId | undefined
