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 boolean 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 handler that scrolls the focused input into the visible area between the safe top and the soft keyboard.

Reads --euv-keyboard-height (set by the native host / IMMERSIVE_SAFE_AREA_SCRIPT page bridge) and the visual viewport. If the input’s bottom edge falls under viewport_bottom - keyboard_height - FOCUS_GAP_PX, the page is scrolled by the difference. A small inline padding-bottom is also added to <main> (when one exists) so the document gains enough scrollable space for the adjustment — the inline style is cleared by Self::on_blur_restore_height.

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

Blur handler that strips the inline padding-bottom injected by Self::on_focus_scroll_into_view so the page returns to its native layout once the keyboard closes.

Trait Implementations
