Struct DebugContext

pub struct DebugContext { /* private fields */ }

A widget that can provide extra information when debugging.

Implementations

impl DebugContext

pub fn dbg<T>(&self, label: impl Into<String>, value: Dynamic<T>) -> Dynamic<T>

where T: Clone + Debug + Send + Sync + 'static,

Observes value by showing the Debug output. Returns value.

When the final reference to value is dropped, this observation will automatically be removed.

This function is designed to work similarly to the dbg! macro.

pub fn observe<T, Widget, MakeObserver>( &self, label: impl Into<String>, value: &Dynamic<T>, make_observer: MakeObserver, )

where T: Clone + Send + Sync + 'static, MakeObserver: FnOnce(Dynamic<T>) -> Widget, Widget: MakeWidget,

Observes value by attaching the widget created by make_observer to this context.

When the final reference to value is dropped, this observation will automatically be removed.

pub fn section(&self, label: impl Into<String>) -> Self

Returns a new child context with the given label.

This creates a nested hierarchy of debug contexts. If a section with the name already exists, a context for the existing section will be returned.

pub fn is_empty(&self) -> bool

Returns true if this debug context has no child sections or observed values.

Trait Implementations

impl Clone for DebugContext

fn clone(&self) -> DebugContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for DebugContext

fn default() -> DebugContext

Returns the “default value” for a type.

impl Drop for DebugContext

fn drop(&mut self)

Executes the destructor for this type.

impl MakeWindow for DebugContext

type Behavior = WidgetInstance

The behavior associated with this window.

fn make_window(self) -> Window<Self::Behavior>

Returns a new window from self.

fn open_centered<App>(self, app: &mut App) -> Result<WindowHandle>

where Self: Sized, App: Application + ?Sized,

Opens self in the center of the monitor the window initially appears on.

fn run_centered(self) -> Result

where Self: Sized,

Runs self in the center of the monitor the window initially appears on.

fn run_centered_in(self, app: PendingApp) -> Result

where Self: Sized,
