Options

Most functions in Leptos-Use come with a version ..._with_options. For example use_css_var has a version use_css_var_with_options. As the name suggests, you can provide additional options to those versions of the functions.

These options are defined as structs with the corresponding PascalCase name. For our example use_css_var_with_options the name of the struct is UseCssVarOptions. Every option struct implements Default and the builder pattern to make it easy to change only the values needed. This can look like the following example.

#![allow(unused)]
fn main() {
let (color, set_color) = use_css_var_with_options(
    "--color",
    UseCssVarOptions::default()
        .target(el)
        .initial_value("#eee"),
);
}

Here only the values target and initial_value are changed and everything else is left to default.
