Enum MultiThemeStrategy 

pub enum MultiThemeStrategy {
    Split,
    CssVars,
}

How multi-theme pretty-code output is laid out in the DOM.

• CssVars (default, fast): single <pre><code> tree. Each styled token carries style="--dmc-light:#XXX;--dmc-dark:#YYY", the <pre> carries default color/background-color from the primary mode. Consumer CSS swaps themes by overriding color to the matching --dmc-* variable inside whichever class / media-query controls the theme. ~25% faster than Split.
• Split (velite parity): one full <pre data-theme="<mode>"><code>...</code></pre> subtree per theme, each with solid color:#XXX per token. Matches velite + rehype-pretty-code byte-for-byte; consumer CSS shows/hides whole panes by [data-theme].

Variants

Split

One <pre data-theme="<mode>">...</pre> subtree per theme. Each subtree carries solid color:#XXX styles, no CSS custom properties. Default because the per-token style strings stay shorter (no --dmc-{mode} pairs), the consumer flips themes by toggling a single [data-theme] CSS rule, and it matches the velite + rehype-pretty-code byte shape that consumers were already styled for. The phase-6 flamegraph confirms PrettyCode dominates compile time, so cutting the per-token work - even at the cost of duplicated pre subtrees - is the right default.

CssVars

One <pre> subtree carrying --dmc-{mode} / --dmc-{mode}-bg custom properties per token, plus solid fallbacks for the default_mode. Consumer CSS toggles via var(--dmc-active). Slightly larger per-token style strings, but only one DOM subtree regardless of theme count - pick this when you have >2 themes or need media-query / class-toggle theme switching without re-rendering the code surface.

Trait Implementations

impl Clone for MultiThemeStrategy

fn clone(&self) -> MultiThemeStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MultiThemeStrategy

impl Debug for MultiThemeStrategy

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

Formats the value using the given formatter.

impl Default for MultiThemeStrategy

fn default() -> MultiThemeStrategy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MultiThemeStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MultiThemeStrategy

impl PartialEq for MultiThemeStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
