Struct FileTreeViewProps 

pub struct FileTreeViewProps {
    pub layout: LayoutStyle,
    pub row_height: Px,
    pub overscan: u32,
    pub keep_alive: Option<usize>,
    pub debug_root_test_id: Option<Arc<str>>,
    pub debug_row_test_id_prefix: Option<Arc<str>>,
}

A retained-host, cache-root friendly file-tree list helper.

This is a pragmatic “workspace surface” building block:

• row identity is TreeItemId,
• click selects, and folders also toggle expansion on click,
• virtualization uses the virt-003 retained host path (so overscan boundary updates can attach/detach without rerendering a parent cache root).

debug_row_test_id_prefix is intended for scripted harnesses (e.g. UI Gallery torture pages).

Fields

layout: LayoutStyle

row_height: Px

overscan: u32

keep_alive: Option<usize>

Optional retained-subtree budget for VirtualList window shifts.

When set, this overrides the default heuristic (overscan * 2). Larger values reduce remount/layout churn at window boundaries, at the cost of retaining more offscreen subtrees.

debug_root_test_id: Option<Arc<str>>

debug_row_test_id_prefix: Option<Arc<str>>
