Crate euv_core 

euv

A declarative, cross-platform UI framework for Rust with virtual DOM, reactive signals, and HTML macros for WebAssembly.

Structs

AttrValueAdapter

Adapts an arbitrary attribute value expression into an AttributeValue.

AttributeEntry

Represents a single attribute on a virtual DOM node.

CssClass

Represents a CSS class with a name, its style declarations, and optional pseudo rules.

DynamicNode

A closure-based dynamic node that re-renders when its dependency signals change.

EventAdapter

Adapts various event value types into an AttributeValue for event attributes.

HookContext

Manages hook state across render cycles for a DynamicNode.

HookContextCell

A Sync wrapper for single-threaded global HookContextInner access.

HookContextInner

Internal storage for hook state, holding boxed Any values.

MediaRule

Represents a CSS @media rule attached to a class.

NativeChangeEvent

Data associated with a change event.

NativeClipboardEvent

Data associated with a clipboard event.

NativeDragEvent

Data associated with a drag event.

NativeEventHandler

A wrapper around an event callback.

NativeFocusEvent

Data associated with a focus event.

NativeInputEvent

Data associated with an input event.

NativeKeyboardEvent

Data associated with a keyboard event.

NativeMediaEvent

Data associated with a media event.

NativeMouseEvent

Data associated with a mouse event.

NativeSubmitEvent

Data associated with a form submit event.

NativeTouchEvent

Data associated with a touch event.

NativeWheelEvent

Data associated with a wheel event.

PseudoRule

Represents a CSS pseudo-class or pseudo-element rule attached to a class.

Renderer

Manages the rendering of virtual DOM nodes to the real DOM.

Signal

A reactive signal handle.

SignalCell

A Sync wrapper for single-threaded global Signal access.

Style

A collection of CSS style properties that can be converted to a style string.

StyleProperty

Represents a CSS style property.

TextNode

Represents a text node in the virtual DOM.

Enums

AttributeValue

Represents the value of an HTML attribute.

NativeEvent

Represents different kinds of UI events.

NativeEventName

Represents the name of a DOM event.

Tag

Represents the type of an HTML tag or a component.

VirtualNode

Represents a node in the virtual DOM tree.

Traits

AsNode

Trait for types that can be converted into a VirtualNode for use in HTML expressions.

AsReactiveText

Trait for types that can be converted into a reactive text VirtualNode.

IntoCallbackAttribute

Trait for types that can be converted into a callback attribute value.

IntoNode

Trait for converting a value into a VirtualNode by consuming it.

IntoReactiveString

Trait for converting a value into a string for reactive attribute updates.

IntoReactiveValue

Trait for types that can be converted into a reactive string value.

Functions

create_dynamic_node

Constructs a VirtualNode::Dynamic from a render closure with hook context management.

create_dynamic_node_with_context

Constructs a VirtualNode::Dynamic for match expressions where arm hook isolation is required. The render closure receives a &mut HookContext so it can call set_arm_changed before each arm body.

create_hook_context

Creates a new HookContext allocated via Box::leak.

create_reactive_attr_signal

Creates a reactive attribute AttributeValue for conditional attribute values.

create_reactive_style_attribute

Creates a reactive style AttributeValue that updates when signals change.

get_current_hook_context

Returns the currently active HookContext.

mount

Mounts the given virtual DOM tree to a specific element matched by a CSS selector.

mount_body

Mounts the given virtual DOM tree to the document body.

subscribe_attr_signal

Subscribes an attribute signal to the global __euv_signal_update__ event so that whenever any signal changes, the attribute value is recomputed and the attribute signal is updated. This enables reactive if conditions inside any HTML attribute, including style, class, and others.

use_signal

Creates a new reactive signal with the given initial value.

with_hook_context

Runs a closure with the given HookContext set as the active context.

with_suppressed_updates

Executes a closure with signal update scheduling suppressed.
