Struct procss::ast::Css

pub struct Css<'a>(pub Vec<FlatRuleset<'a>>);

A non-nested “flat” CSS representation, suitable for browser output. The Css AST is typically generated via the crate::ast::Tree::flatten_tree method.

Tuple Fields

0: Vec<FlatRuleset<'a>>

Implementations

impl<'a> Css<'a>

pub fn transform<T>(&mut self, f: impl FnMut(&mut T))where
    Self: TransformCss<T>,

A mutable transform which walks this AST recursively, invoking f for all nodes of type T.

Example

use procss::{ast, parse, RenderCss};
let mut css = parse("div{color: red;}").unwrap().flatten_tree();
css.transform(|rule: &mut ast::Rule| {
    rule.value = "green".into();
});

assert_eq!(css.as_css_string(), "div{color:green;}");

pub fn iter(&self) -> impl Iterator<Item = &FlatRuleset<'a>>

Iterate over the immediate children of this Tree (non-recursive).

Trait Implementations

impl<'a> Debug for Css<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> RenderCss for Css<'a>

fn render(&self, f: &mut Formatter<'_>) -> Result

fn as_css_string(&self) -> String

Render self as a valid CSS String, minified (with non-interpretation-impacting whitespace removed).
