Enum SessionVisibility 

pub enum SessionVisibility {
    Shared,
    OptIn,
}

Whether a session is shown to every view or only to the ones that ask for it.

The default is Shared, and it is the right default: a spell-checker’s squiggles and a comment’s underline are facts about the text, so every view of that text should draw them.

OptIn is for a layer that is a fact about one view rather than about the text: a reading that marks every mention of one character, say. Such a layer still lives on the document (there is nowhere else for a range session to live), but a mask has to name it before anything renders it, so a second view of the same document is left alone. Without this the only way to keep a layer out of a sibling view would be HighlightMask::only, which means naming every session the view does want, including ones it has no handle on, such as the widget’s own ambient caret band.

Variants

Shared

Rendered by every view whose mask does not exclude it. The default.

OptIn

Rendered only by a view whose mask names it. See HighlightMask::with.
