Struct CssStyle 

pub struct CssStyle { /* private fields */ }

A type alias representing CSS style properties for HTML nodes in KaTeX rendering.

This HashMap maps CSS property names (as strings) to their corresponding values, enabling dynamic styling of mathematical expressions rendered as HTML. It is used throughout the KaTeX rendering pipeline to apply visual styles such as colors, fonts, spacing, and positioning to generated HTML elements.

LaTeX/KaTeX Context

In mathematical typesetting, CSS styles are crucial for controlling the visual appearance of rendered math, including font variants (e.g., italic for variables), display styles (inline vs. block), and layout adjustments. This type supports KaTeX’s approach to generating accessible and visually consistent math output.

Implementations

impl CssStyle

pub fn with_capacity(capacity: usize) -> Self

Creates one with given capacity

pub fn insert<T>(&mut self, property: CssProperty, value: T)

where T: Into<String>,

Inserts or updates a CSS property with the given value.

pub fn contains_key(&self, property: CssProperty) -> bool

Checks if the style contains a specific CSS property.

pub fn get(&self, property: CssProperty) -> Option<&str>

Retrieves the value of a specific CSS property, if it exists.

pub fn is_empty(&self) -> bool

Checks if the style is empty (contains no properties).

pub fn write_to<W: Write>(&self, writer: &mut W) -> Result

Writes the CSS style as a string to the provided formatter.

Trait Implementations

impl Clone for CssStyle

fn clone(&self) -> CssStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CssStyle

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

Formats the value using the given formatter.

impl Default for CssStyle

fn default() -> CssStyle

Returns the “default value” for a type.

impl Display for CssStyle

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

Formats the value using the given formatter.

impl PartialEq for CssStyle

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