Enum TreeCountingFunction 

#[repr(u8)]
pub enum TreeCountingFunction {
    SiblingCount = 0,
    SiblingIndex = 1,
}

A CSS tree-counting function: sibling-index() or sibling-count(). See https://www.w3.org/TR/css-values-5/#tree-counting.

Variants

SiblingCount = 0

sibling-count(): the total number of siblings of the element, including itself.

SiblingIndex = 1

sibling-index(): the 1-based index of the element among its siblings.

Implementations

impl TreeCountingFunction

pub fn to_computed_value(&self, context: &Context<'_>) -> u32

Computes the value of this tree-counting function.

Trait Implementations

impl Clone for TreeCountingFunction

fn clone(&self) -> TreeCountingFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreeCountingFunction

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

Formats the value using the given formatter.

impl MallocSizeOf for TreeCountingFunction

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 TreeCountingFunction

fn eq(&self, other: &TreeCountingFunction) -> 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 TreeCountingFunction

fn partial_cmp(&self, other: &TreeCountingFunction) -> 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.

impl ToCss for TreeCountingFunction

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl ToShmem for TreeCountingFunction

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl ToTyped for TreeCountingFunction

fn to_typed(&self, dest: &mut ThinVec<TypedValue>) -> Result<(), ()>

Attempt to convert self into one or more TypedValue items.

fn to_typed_value(&self) -> Option<TypedValue>

Attempt to convert self into a TypedValue.

fn to_numeric_value(&self) -> Option<NumericValue>

Attempt to convert self into a NumericValue.

fn to_typed_value_list(&self) -> Option<TypedValueList>

Attempt to convert self into a TypedValueList.
