Trait Backend

pub trait Backend<T: Theme>: 'static {
    // Required methods
    fn replace_all(&mut self, css: String);
    fn run_css_generator(
        &mut self,
        generator: CssGeneratorFn<T>,
        theme: &T,
        counter: &mut u64,
    );
}

css-in-rs is backend agnostic. The default backend is based on web_sys, but other backends are possible (i.e. just insert css into a string, for example for server side rendering).

Required Methods

fn replace_all(&mut self, css: String)

Replaces all styles managed by this backend by the given CSS string

fn run_css_generator( &mut self, generator: CssGeneratorFn<T>, theme: &T, counter: &mut u64, )

Runs a given css generator and add the generated styles. The generator function is expected to append new rules to the given String. It may be empty, in which case the new style is to be returned. Alternatively, the backend may choose to put in all existing rules, in which case the new rules are to be appended.
