Struct AttrValueAdapter 

pub struct AttrValueAdapter<T> { /* private fields */ }

Adapts an arbitrary attribute value expression into an AttributeValue.

Handles the dispatch between event closures and reactive values without requiring the macro to generate inline trait hierarchies. The macro emits AttrValueAdapter::new(expr).into_attribute_value() instead of the __IsClosure / __ClosurePicker / __ValuePicker / __FallbackHelper / __dispatch boilerplate.

For event attributes (key starts with “on”), event closures are wrapped into AttributeValue::Event. For non-event attributes, values are converted via IntoReactiveValue.

Implementations

impl<T> AttrValueAdapter<T>

pub fn get_mut_inner(&mut self) -> &mut T

impl<T> AttrValueAdapter<T>

pub fn new(inner: T) -> Self

impl<F> AttrValueAdapter<F>

where F: FnMut(Event) + 'static,

Adapts a FnMut(Event) closure into a callback AttributeValue.

This handles the case where a closure is used as a component callback prop. The closure is converted via IntoCallbackAttribute::into_callback_attribute().

pub fn into_callback_attribute_value(self) -> AttributeValue

Converts the wrapped closure into a callback AttributeValue.

Returns

• AttributeValue - An event attribute value wrapping the adapted closure.

pub fn into_callback_attribute_value_with_name( self, name: &'static str, ) -> AttributeValue

Converts the wrapped closure into a callback AttributeValue with a custom event name for component props.

Arguments

• &'static str - The custom attribute name (e.g., “on-increment”, “on-change”).

Returns

• AttributeValue - An event attribute value with the custom name.

impl AttrValueAdapter<NativeEventHandler>

Adapts an owned NativeEventHandler into an AttributeValue::Event directly.

pub fn into_callback_attribute_value(self) -> AttributeValue

Converts the wrapped handler into an event AttributeValue.

Returns

• AttributeValue - An AttributeValue::Event containing the re-wrapped handler.

pub fn into_callback_attribute_value_with_name( self, name: &'static str, ) -> AttributeValue

Converts the wrapped handler into a callback AttributeValue with a custom event name for component props.

Arguments

• &'static str - The custom attribute name.

Returns

• AttributeValue - An event attribute value with the custom name.

impl AttrValueAdapter<Option<NativeEventHandler>>

Adapts an Option<NativeEventHandler> into an AttributeValue.

pub fn into_callback_attribute_value(self) -> AttributeValue

Converts the wrapped optional handler into an attribute value.

Returns

• AttributeValue - An event attribute if Some, otherwise an empty text attribute.

pub fn into_callback_attribute_value_with_name( self, name: &'static str, ) -> AttributeValue

Converts this optional handler into a callback AttributeValue with a custom event name for component props.

Arguments

• &'static str - The custom attribute name.

Returns

• AttributeValue - An event attribute with the custom name if Some, otherwise an empty text attribute.

impl<T> AttrValueAdapter<T>

where T: IntoReactiveValue,

Adapts any IntoReactiveValue type into an AttributeValue.

This is the fallback path for non-closure attribute values (strings, signals, CSS classes, etc.). The value is converted via IntoReactiveValue::into_reactive_value().

pub fn into_reactive_attribute_value(self) -> AttributeValue

Converts the wrapped value into an AttributeValue via reactive value adaptation.

Returns

• AttributeValue - The reactive attribute value.

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

Formats the value using the given formatter.
