Implementations

impl Tree

pub fn of<A>(_action: A) -> Self

where A: Action<Input = TreeQuery, Output = Result<Vec<TreeItem>>>,

pub fn label(self, label: impl Into<Text>) -> Self

The tree’s accessible name.

Trait Implementations

impl Component for Tree

fn render(&self, out: &mut String, r: &Render<'_>)

fn schema(&self) -> Json

Schema used by MCP tools and test generation. Include a "type" key.

fn source(&self, key: &str) -> Option<&dyn DataSource>

Data the component fetches through an action, by key (a field name for lookups).

fn grid(&self) -> Option<&dyn GridSource>

fn form(&self) -> Option<&dyn FormSource>

fn reveal(&self, _field: &str) -> Option<Revealed>

The raw value of a masked field this component shows, for an audited reveal. The server checks the unmask permission before sending it.

fn import(&self) -> Option<&dyn ImportSource>

CSV import, for components that import rows (see crate::Import).

fn children(&self) -> &[Node]

Nodes held by a container. Child i of the node at path p has the path p.i.

fn eager_children(&self) -> &[Node]

Children rendered with the page. Others, such as closed lazy tabs, load when first shown.

fn shortcuts(&self) -> Vec<&str>

Keyboard shortcuts of the component’s own links, as declared, for the clash checks of App::check and App::check_page.

impl From<Tree> for Node

fn from(c: Tree) -> Self

Converts to this type from the input type.
