Struct Css 

#[repr(C)]
pub struct Css {
    pub rules: CssRuleBlockVec,
}

Css stylesheet - contains a parsed CSS stylesheet in “rule blocks”, i.e. blocks of key-value pairs associated with a selector path.

Layer separation (UA / system / author / inline / runtime) is encoded per-rule via CssRuleBlock::priority; see rule_priority for the slot allocation. There is no separate Stylesheet wrapper — to merge two CSS sources, concatenate their rules and re-sort.

Fields

rules: CssRuleBlockVec

All rule blocks, in source order. Sort by (priority, specificity) via sort_by_specificity to put them in cascade order.

Implementations

impl Css

pub fn is_empty(&self) -> bool

pub fn new(rules: Vec<CssRuleBlock>) -> Self

pub fn from_string(s: AzString) -> Self

pub fn parse_inline(style: &str) -> Self

Parse inline-style CSS (bare properties, pseudo blocks, @-rule blocks) and return a Css whose rules carry rule_priority::INLINE.

Wraps the input in * { ... } so the main CSS parser can handle bare properties at the top level. Pseudo and at-rule blocks like :hover { color: red; } or @os(linux) { font-size: 14px; } work directly via CSS nesting.

pub fn from_string_with_warnings( s: AzString, ) -> (Self, Vec<CssParseWarnMsgOwned>)

impl Css

pub fn empty() -> Self

Creates a new, empty CSS.

pub fn sort_by_specificity(&mut self)

Sort the rules by (priority, specificity) so they apply in cascade order. Lower-priority rules sort first; ties break by selector specificity. This preserves layer identity (UA / SYSTEM / AUTHOR / INLINE / RUNTIME) without needing a separate Stylesheet boundary.

pub fn rules<'a>(&'a self) -> Iter<'a, CssRuleBlock>

pub fn iter_inline_properties<'a>( &'a self, ) -> impl Iterator<Item = (&'a CssProperty, &'a DynamicSelectorVec)> + 'a

Iterate (property, conditions) pairs as if this were a flat list of CssPropertyWithConditions. Each Static declaration yields one item, sharing the conditions of its enclosing rule. Dynamic declarations are skipped (matching the previous inline-CSS behaviour).

Used by cascade and diff code that walks per-property to keep the flat-iteration shape after the inline-vs-component unification.

Trait Implementations

impl Clone for Css

fn clone(&self) -> Css

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Css

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

Formats the value using the given formatter.

impl Default for Css

fn default() -> Css

Returns the “default value” for a type.

impl Extend<Css> for CssVec

fn extend<T: IntoIterator<Item = Css>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<CssPropertyWithConditionsVec> for Css

Convert a flat list of CssPropertyWithConditions (the legacy inline-CSS form) into a Css. Each property becomes a single-declaration CssRuleBlock with priority = INLINE, an empty path (implicitly :scope — applies to the node it lives on), and the original conditions intact.

This bridge lets widget code that built &[CssPropertyWithConditions] arrays keep working through .into() while the storage on NodeData is the unified Css type.

fn from(props: CssPropertyWithConditionsVec) -> Self

Converts to this type from the input type.

impl From<Vec<CssRuleBlock>> for Css

fn from(rules: Vec<CssRuleBlock>) -> Self

Converts to this type from the input type.

impl FromIterator<Css> for CssVec

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = Css>,

Creates a value from an iterator.

impl Ord for Css

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Css

fn eq(&self, other: &Css) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Css

fn partial_cmp(&self, other: &Css) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
