    fn should_skip(&self) -> bool;

Expand description

A trait for types that can be used as parts of a CSS class attribute.

This trait enables different types to participate in class merging via the classes! macro. Implementations handle how each type writes its class value and whether it should be skipped.

§Provided Implementations

  • &str: Writes the string directly. Skipped if the string is empty.
  • Option<&str>: Writes the inner string if Some, skipped if None or empty.

§Example

use plait::{html, classes, render};

let base = "btn";
let variant = Some("btn-primary");
let disabled: Option<&str> = None;

let html = render(html! {
    button(class: classes!(base, variant, disabled)) { "Click" }
});

assert_eq!(html, "<button class=\"btn btn-primary\">Click</button>");
