Crate rcss_layers

Layered CSS representation Uses information from ScopeChain or one that user provide to build a layered representation of styles.

Example:

use crate::*;
let mut chain = LayeredCss::new();
chain.add_style_from_parts("root", 0, "root", "style1{color:red}");
chain.add_style_from_parts("root", 1, "layer2", "style2{color:blue}");
chain.add_style_from_parts("root", 2, "layer3", "style3{color:green}");
let representation = chain
      .styles
      .get("root")
      .unwrap()
      .render(false, "root")
      .unwrap();
let mut expectation = String::from("@layer root,layer2,layer3;");
expectation.push_str("@layer root{style1{color:red}}");
expectation.push_str("@layer layer2{style2{color:blue}}");
expectation.push_str("@layer layer3{style3{color:green}}");
assert_eq!(representation, expectation);

Structs

• LayeredCss
• StyleTree
  Store chain of extensions.

Type Aliases

• Order
  Order of layers is determined by how far a layer is from root.
• ScopeId
  Identifier of scoped style. rcss uses &'static str as scope_id but we use Cow<'static, str> to support dynamic extension.
• Style
  Style representation. rcss uses &'static str as style representation but we use Cow<'static, str> to support dynamic extension.
