Struct RenderOutput 

pub struct RenderOutput {
    pub attrs: Vec<(String, AttrValue)>,
    pub classes: Vec<String>,
    pub aria: AriaAttributes,
    pub children: ChildrenSpec,
    pub data_attrs: Vec<(String, String)>,
    pub tag: Option<String>,
    pub styles: Vec<(String, String)>,
}

Framework-agnostic render description produced by components.

A RenderOutput describes what a component looks like without committing to any specific framework’s rendering model. Framework adapters translate this into Leptos view! or Dioxus rsx! output.

Fields

attrs: Vec<(String, AttrValue)>

HTML attributes to set on the root element.

classes: Vec<String>

CSS class names to add to the root element.

aria: AriaAttributes

ARIA attributes for accessibility.

children: ChildrenSpec

Child content specification.

data_attrs: Vec<(String, String)>

Data attributes (data-*) for testing and JS interop.

tag: Option<String>

The HTML tag name to render (default: “div”).

styles: Vec<(String, String)>

Inline styles (escape hatch — prefer classes).

Implementations

impl RenderOutput

pub fn new() -> Self

Create a new empty RenderOutput.

pub fn with_tag(self, tag: impl Into<String>) -> Self

Set the HTML tag name.

pub fn with_attr(self, name: impl Into<String>, value: AttrValue) -> Self

Add an HTML attribute.

pub fn with_class(self, class: impl Into<String>) -> Self

Add a CSS class.

Validates the class name to prevent CSS injection. Invalid class names are silently dropped. Use crate::security::is_safe_class_name to check before calling if you need to handle the error.

pub fn with_classes( self, classes: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Add multiple CSS classes.

Each class is validated individually via crate::security::is_safe_class_name. Invalid class names are silently dropped.

pub fn with_aria(self, aria: AriaAttributes) -> Self

Set the ARIA attributes.

pub fn with_children(self, children: ChildrenSpec) -> Self

Set the children specification.

pub fn with_data( self, name: impl Into<String>, value: impl Into<String>, ) -> Self

Add a data attribute.

pub fn with_style( self, property: impl Into<String>, value: impl Into<String>, ) -> Self

Add an inline style.

Validates the value to prevent CSS injection. Unsafe values (containing expression(), url(), javascript:, etc.) are silently dropped.

pub fn effective_tag(&self) -> &str

Get the effective tag name (defaults to “div”).

pub fn class_string(&self) -> String

Get all classes as a single space-separated string.

pub fn style_string(&self) -> String

Get all inline styles as a CSS string.

pub fn merge(self, other: RenderOutput) -> Self

Merge another RenderOutput into this one.

Attributes, classes, data attributes, and styles are appended. ARIA attributes from other overwrite self where set. Tag and children from other take precedence if set.

Trait Implementations

impl Clone for RenderOutput

fn clone(&self) -> RenderOutput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderOutput

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

Formats the value using the given formatter.

impl Default for RenderOutput

fn default() -> RenderOutput

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RenderOutput

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RenderOutput

fn eq(&self, other: &RenderOutput) -> 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 Serialize for RenderOutput

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
