Struct UseEuvInput 

pub struct UseEuvInput;

Input functionality for handling form input events.

Provides methods for creating toggle handlers, input value handlers, and focus/blur event handlers.

Implementations

impl UseEuvInput

Implementation of input functionality.

pub fn use_toggle(signal: Signal<bool>) -> Option<Rc<dyn Fn(Event)>>

Creates a click event handler that toggles a boolean signal.

Produces a NativeEventHandler that flips the value of the given boolean signal on each click. Useful for toggle buttons, visibility switches, and drawer open/close patterns.

Arguments

• Signal<bool> - The boolean signal to toggle.

Returns

• Option<Rc<dyn Fn(Event)>> - A click event handler that toggles the signal.

pub fn on_input_value(signal: Signal<String>) -> Option<Rc<dyn Fn(Event)>>

Creates an input event handler that updates a string signal.

Arguments

• Signal<String> - The signal to update with the input value.

Returns

• Option<Rc<dyn Fn(Event)>> - An input handler.

pub fn on_change_value(signal: Signal<String>) -> Option<Rc<dyn Fn(Event)>>

Creates a change event handler that updates a string signal.

Arguments

• Signal<String> - The signal to update with the change value.

Returns

• Option<Rc<dyn Fn(Event)>> - A change handler.

pub fn on_change_checked(signal: Signal<bool>) -> Option<Rc<dyn Fn(Event)>>

Creates a change event handler that updates a boolean signal from checkbox.

Arguments

• Signal<bool> - The signal to update with the checked state.

Returns

• Option<Rc<dyn Fn(Event)>> - A change handler.

pub fn on_focus_scroll_into_view() -> Option<Rc<dyn Fn(Event)>>

Creates a focus event handler that scrolls the focused input into view.

On mobile devices, focusing an input can open the virtual keyboard and obscure the field. This handler waits briefly for the keyboard to appear, then checks whether the input’s bottom edge is below the visible viewport (using VisualViewport when available). If so, it scrolls the page just enough to leave a small gap between the input and the keyboard.

Returns

• Option<Rc<dyn Fn(Event)>> - A focus handler.

pub fn on_blur_restore_height() -> Option<Rc<dyn Fn(Event)>>

Creates a blur event handler that restores the page height after input focus.

Removes the temporary padding-bottom injected by on_focus_scroll_into_view so that the page returns to its original height once the virtual keyboard is dismissed.

Returns

• Option<Rc<dyn Fn(Event)>> - A blur handler.

Trait Implementations

impl Clone for UseEuvInput

fn clone(&self) -> UseEuvInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UseEuvInput

impl Debug for UseEuvInput

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

Formats the value using the given formatter.

impl Default for UseEuvInput

fn default() -> UseEuvInput

Returns the “default value” for a type.

impl Eq for UseEuvInput

impl Hash for UseEuvInput

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 Ord for UseEuvInput

fn cmp(&self, other: &UseEuvInput) -> 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 UseEuvInput

fn eq(&self, other: &UseEuvInput) -> 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 UseEuvInput

fn partial_cmp(&self, other: &UseEuvInput) -> 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.
