Struct style::custom_properties_map::CustomPropertiesMap

pub struct CustomPropertiesMap(Arc<Inner>);

A map for a set of custom properties, which implements copy-on-write behavior on insertion with cheap copying.

Tuple Fields

0: Arc<Inner>

Implementations

impl CustomPropertiesMap

pub fn is_empty(&self) -> bool

Returns whether the map has no properties in it.

pub fn len(&self) -> usize

Returns the amount of different properties in the map.

pub fn get_index( &self, index: usize, ) -> Option<(&Name, &Option<ComputedRegisteredValue>)>

Returns the property name and value at a given index.

pub fn get(&self, name: &Name) -> Option<&ComputedRegisteredValue>

Returns a given property value by name.

fn do_insert(&mut self, name: &Name, value: Option<ComputedRegisteredValue>)

pub fn insert(&mut self, name: &Name, value: ComputedRegisteredValue)

Inserts an element in the map.

pub fn remove(&mut self, name: &Name)

Removes an element from the map.

pub fn shrink_to_fit(&mut self)

Shrinks the map as much as possible.

pub fn iter(&self) -> Iter<'_>

Return iterator to go through all properties.

Trait Implementations

impl Clone for CustomPropertiesMap

fn clone(&self) -> CustomPropertiesMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CustomPropertiesMap

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

Formats the value using the given formatter.

impl Default for CustomPropertiesMap

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CustomPropertiesMap

fn eq(&self, other: &CustomPropertiesMap) -> 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.
