Enum TreePatch 

pub enum TreePatch {
    Reload,
    Expand(u64, bool),
    Selected(Vec<u64>),
    Reveal(u64),
}

Post-realize changes to a kinds::TREE host (docs/tree.md). Token-addressed throughout; see crate::TreeSource for why indices cannot address tree rows.

Variants

Reload

The node set changed (count/order/parentage/content): the host re-queries its TreeSource. Expansion and selection survive by token (docs/tree.md).

Expand(u64, bool)

Programmatically disclose (true) or collapse (false) one row. Applied without re-emitting crate::Event::TreeExpanded (the from-native echo rule).

Selected(Vec<u64>)

Programmatic selection sync (tokens; empty = clear), applied without re-emitting crate::Event::TreeSelection.

Reveal(u64)

Scroll this row into view, realizing it if needed. The piece has already expanded the row’s ancestors (through the app’s expansion signal) before issuing this.
