Struct WidgetId

pub struct WidgetId(/* private fields */);

The unique id of a WidgetInstance.

Each WidgetInstance is guaranteed to have a unique WidgetId across the lifetime of an application.

Implementations

impl WidgetId

pub fn find_in(self, context: &WidgetContext<'_>) -> Option<MountedWidget>

Finds this widget mounted in this window, if present.

Trait Implementations

impl AsRef<WidgetId> for MountedWidget

fn as_ref(&self) -> &WidgetId

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<WidgetId> for WidgetInstance

fn as_ref(&self) -> &WidgetId

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<WidgetId> for WidgetRef

fn as_ref(&self) -> &WidgetId

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for WidgetId

fn clone(&self) -> WidgetId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetId

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

Formats the value using the given formatter.

impl From<WidgetTag> for WidgetId

fn from(value: WidgetTag) -> Self

Converts to this type from the input type.

impl Hash for WidgetId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl ManageWidget for WidgetId

type Managed = Option<MountedWidget>

The managed type, which can be Option<MountedWidget> or MountedWidget.

fn manage(&self, context: &WidgetContext<'_>) -> Self::Managed

Resolve self into a MountedWidget.

impl Ord for WidgetId

fn cmp(&self, other: &WidgetId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WidgetId

fn eq(&self, other: &WidgetId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for WidgetId

fn partial_cmp(&self, other: &WidgetId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
