Struct style::applicable_declarations::ApplicableDeclarationBlock

pub struct ApplicableDeclarationBlock {
    pub source: StyleSource,
    pub specificity: u32,
    // some fields omitted
}

A property declaration together with its precedence among rules of equal specificity so that we can sort them.

This represents the declarations in a given declaration block for a given importance.

Fields

source: StyleSource

The style source, either a style rule, or a property declaration block.

specificity: u32

The specificity of the selector this block is represented by.

Methods

impl ApplicableDeclarationBlock

pub fn from_declarations(
    declarations: Arc<Locked<PropertyDeclarationBlock>>,
    level: CascadeLevel
) -> Self

Constructs an applicable declaration block from a given property declaration block and importance.

pub fn new(
    source: StyleSource,
    order: u32,
    level: CascadeLevel,
    specificity: u32
) -> Self

Constructs an applicable declaration block from the given components

pub fn source_order(&self) -> u32

Returns the source order of the block.

pub fn level(&self) -> CascadeLevel

Returns the cascade level of the block.

pub fn order_and_level(self) -> (StyleSource, CascadeLevel)

Convenience method to consume self and return the source alongside the level.

Trait Implementations

impl Clone for ApplicableDeclarationBlock

fn clone(&self) -> ApplicableDeclarationBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ApplicableDeclarationBlock

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl MallocSizeOf for ApplicableDeclarationBlock

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for ApplicableDeclarationBlock

fn eq(&self, __arg_0: &ApplicableDeclarationBlock) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &ApplicableDeclarationBlock) -> bool

This method tests for !=.
