Struct ThemeScript 

Source 
pub struct ThemeScript { /* private fields */ }
Expand description

The pre-paint theme script.

Runs before the first paint so the page never flashes the wrong theme, which is why it is inline and blocking rather than a module at the end of body.

It stamps data-theme on <html> in exactly two of three cases:

  1. the reader chose a theme — stamp it;
  2. the reader chose nothing but the OS states a preference — stamp nothing, so the stylesheet’s media queries stay live and follow the OS if it changes mid-session;
  3. neither states anything — stamp Fallback.

What [data-theme="dark"] means is entirely the project’s CSS. This type owns only the handshake.

Implementations§

Source§

impl ThemeScript

Source

pub const fn new(fallback: Fallback) -> Self

A script that falls back to fallback when nothing states a preference.

Source

pub fn source(&self) -> String

The JavaScript to inline.

The try wraps only the storage read: browsers with site data blocked throw there, which is an environment, not a bug. Everything after it is left unguarded so a genuine mistake in this crate fails loudly.
