Struct TreeRowDecoration 

pub struct TreeRowDecoration {
    pub icon: Option<TreeRowIcon>,
    pub tone: TreeRowTone,
    pub trailing: Option<String>,
    pub description: Option<String>,
    pub presence: Option<PresenceKey>,
}

Per-row presentation painted by the tree itself: a leading icon, a label tone, trailing secondary text (a count, a type) and an accessible description. Unlike TreeView::with_row_delegate nothing is mounted, so decorations are recomputed every frame at no retained cost; disclosure, selection, hover, the current row, focus and semantics stay owned by the tree.

Fields

icon: Option<TreeRowIcon>

tone: TreeRowTone

trailing: Option<String>

Right-aligned secondary text; the label elides before it.

description: Option<String>

Spoken after the label (e.g. “View”, “Folder”).

presence: Option<PresenceKey>

Collaborators present at this location glow the row in their colour (the peer’s “indicative mist”), so a tree shows where everyone is.
