Struct CssClass 

pub struct CssClass { /* private fields */ }

Represents a CSS class with a name and its style declarations.

Created by the class! macro and used in html! via the class: attribute. When the renderer encounters a CssClass, it injects the styles into the DOM’s <style> element on first use and applies the class name to the element.

Implementations

impl CssClass

Implementation of CssClass construction and style injection.

pub fn new(name: String, style: String) -> Self

Creates a new CSS class with the given name and style declarations.

Automatically injects the styles into the DOM upon creation.

pub fn inject_style(&self)

Injects this class’s styles into the DOM if not already present.

Creates a <style> element with id euv-css-injected on first call, then appends the class rule. Subsequent calls for the same class name are no-ops. On first creation, also injects global CSS keyframes required by built-in animations.

impl CssClass

pub fn get_name(&self) -> &String

pub fn set_name(&mut self, val: String) -> &mut Self

pub fn get_mut_name(&mut self) -> &mut String

pub fn get_style(&self) -> &String

pub fn set_style(&mut self, val: String) -> &mut Self

pub fn get_mut_style(&mut self) -> &mut String

Trait Implementations

impl Clone for CssClass

fn clone(&self) -> CssClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for CssClass

fn default() -> CssClass

Returns the “default value” for a type.

impl Display for CssClass

Displays the CSS class name.

This enables format!("{}", css_class) to produce the class name string, which is required for reactive if conditions in class: attributes.

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

Formats the value using the given formatter.

impl IntoReactiveString for &'static CssClass

Converts a reference to a CssClass into its class name for reactive string storage.

fn into_reactive_string(self) -> String

Converts this value into its string representation for attribute storage.

impl IntoReactiveString for CssClass

Converts a CssClass into its class name for reactive string storage.

fn into_reactive_string(self) -> String

Converts this value into its string representation for attribute storage.

impl IntoReactiveValue for &'static CssClass

Converts a reference to a CSS class into an attribute value by cloning.

fn into_reactive_value(self) -> AttributeValue

Converts this value into an AttributeValue, wrapping signals for reactive updates or converting static values to text.

impl IntoReactiveValue for CssClass

Converts a CSS class reference into an attribute value.

fn into_reactive_value(self) -> AttributeValue

Converts this value into an AttributeValue, wrapping signals for reactive updates or converting static values to text.

impl PartialEq for CssClass

Visual equality comparison for CSS classes.

Two CSS classes are considered equal when their class names match, since the name uniquely identifies the visual style rule.

fn eq(&self, other: &Self) -> 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.
