Struct TreeNode 

pub struct TreeNode {
    pub text: TextPropertyEntry,
    pub depth: u32,
    pub has_children: bool,
    pub checked: Option<bool>,
}

One node in a Tree widget’s flat-list spec. The plugin walks its hierarchy depth-first and emits one TreeNode per node; depth controls indent, has_children controls whether the disclosure glyph (and its hit area) is rendered. The host filters the visible window — descendants of collapsed nodes are skipped.

text is the pre-rendered row content. The host prepends the indent + disclosure glyph at render time and shifts the entry’s inline overlays accordingly; plugins emit text (and overlays) in the row’s own coordinate space, starting at column 0.

Fields

text: TextPropertyEntry

The pre-rendered row content (text + per-row overlays). The host renders this verbatim after the indent + disclosure prefix; plugin overlays are byte-shifted by the prefix length.

depth: u32

0-based depth — controls leading indent (depth * 2 spaces).

has_children: bool

When true, render a disclosure glyph (▶ collapsed / ▼ expanded) and emit a hit area over it that fires the expand event. Leaf nodes (false) get no glyph and no expand hit; the row width occupies the full row.

checked: Option<bool>

Per-node checkbox state. Only rendered when the parent Tree has checkable: true. None = no checkbox glyph; Some(true) = [v]; Some(false) = [ ]. The plugin owns the truth — the host fires widget_event { event_type: "toggle" } and the plugin pushes the new state back via WidgetMutation::SetCheckedKeys.

Trait Implementations

impl Clone for TreeNode

fn clone(&self) -> TreeNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreeNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TreeNode

fn deserialize<__D>( __deserializer: __D, ) -> Result<TreeNode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for TreeNode

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for TreeNode

type WithoutGenerics = TreeNode

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or ().
The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = TreeNode

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident(cfg: &Config) -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name(cfg: &Config) -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete(cfg: &Config) -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl(cfg: &Config) -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline(cfg: &Config) -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened(cfg: &Config) -> String

Flatten a type declaration. This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where TreeNode: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported, relative to the output directory. The returned path does not include any base directory.

fn visit_dependencies(v: &mut impl TypeVisitor)

where TreeNode: 'static,

Iterates over all dependency of this type.

fn dependencies(cfg: &Config) -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies. To export only this type, without its dependencies, use TS::export.

fn export_to_string(cfg: &Config) -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String. This function does not format the output, even if the format feature is enabled.
