AST module.

CSS AST Module

This module defines the Abstract Syntax Tree (AST) structure for CSS code.

AST Nodes

• CssRoot: The root node of the CSS AST, containing a list of top-level nodes.
• CssNode: A variant representing different types of CSS nodes (rule sets, at-rules, comments).
• RuleSet: A CSS rule set consisting of selectors and declarations.
• Declaration: A CSS declaration consisting of a property name and value.
• Selector: A variant representing different types of CSS selectors.
• Value: A variant representing different types of CSS values.
• AtRule: A variant representing different types of CSS at-rules.

Usage

use oak_css::{CssRoot, CssNode, RuleSet, Declaration, Selector, Value};

// Create a simple CSS AST
let ast = CssRoot {
    nodes: vec![
        CssNode::RuleSet(RuleSet {
            selectors: vec![Selector::Element("div".to_string())],
            declarations: vec![Declaration {
                property: "color".to_string(),
                value: Value::Keyword("red".to_string()),
                span: 0..15,
            }],
            span: 0..15,
        }),
    ],
};

Features

• Serde Support: AST nodes can be serialized and deserialized when the serde feature is enabled.
