Struct CustomStyles 

pub struct CustomStyles { /* private fields */ }

The custom style properties set on an element or inherited from its ancestors, keyed by property type.

Every property lives behind one Arc, so cloning a style shares them and an element that sets none carries only a null pointer. A write copies the map before mutating it, so clones never observe each other’s changes.

Implementations

impl CustomStyles

pub fn insert<T>(&mut self, property: T)

where T: CustomStyleProperty,

Sets property, replacing any value already set for its type.

pub fn get<T>(&self) -> Option<&T>

where T: CustomStyleProperty,

Returns the property of type T, if one was set.

pub fn refine(&mut self, other: &CustomStyles)

Merges other into self, letting other win where both set the same type.

Trait Implementations

impl Clone for CustomStyles

fn clone(&self) -> CustomStyles

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomStyles

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

Formats the value using the given formatter.

impl Default for CustomStyles

fn default() -> CustomStyles

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CustomStyles

fn deserialize<D>( deserializer: D, ) -> Result<CustomStyles, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl IsEmpty for CustomStyles

fn is_empty(&self) -> bool

Returns true if applying this refinement would have no effect.

impl JsonSchema for CustomStyles

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn json_schema(_: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl PartialEq for CustomStyles

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

Equality operator ==.

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

Inequality operator !=.

impl Refineable for CustomStyles

type Refinement = CustomStyles

fn refine(&mut self, refinement: &<CustomStyles as Refineable>::Refinement)

Applies the given refinement to this instance, modifying it in place.

fn refined( self, refinement: <CustomStyles as Refineable>::Refinement, ) -> CustomStyles

Returns a new instance with the refinement applied, equivalent to cloning self and calling refine on it.

fn is_superset_of( &self, refinement: &<CustomStyles as Refineable>::Refinement, ) -> bool

Returns true if this instance would contain all values from the refinement.

fn subtract( &self, refinement: &<CustomStyles as Refineable>::Refinement, ) -> <CustomStyles as Refineable>::Refinement

Returns a refinement that represents the difference between this instance and the given refinement.

fn from_cascade(cascade: &Cascade<Self>) -> Self

where Self: Sized + Default,

Creates an instance from a cascade by merging all refinements atop the default value.

impl Serialize for CustomStyles

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
