Enum leptos::Class

pub enum Class {
    Value(bool),
    Fn(Scope, Box<dyn Fn() -> bool + 'static, Global>),
}

Represents the different possible values a single class on an element could have, allowing you to do fine-grained updates to single items in Element.classList.

This mostly exists for the view macro’s use. You usually won’t need to interact with it directly, but it can be useful for defining permissive APIs for certain components.

Variants

Value(bool)

Whether the class is present.

Fn(Scope, Box<dyn Fn() -> bool + 'static, Global>)

A (presumably reactive) function, which will be run inside an effect to toggle the class.

Implementations

impl Class

pub fn as_value_string(&self, class_name: &'static str) -> &'static str

Converts the class to its HTML value at that moment so it can be rendered on the server.
