Struct style::custom_properties::CustomPropertiesBuilder

pub struct CustomPropertiesBuilder<'a> { /* fields omitted */ }

A struct that takes care of encapsulating the cascade process for custom properties.

Methods

impl<'a> CustomPropertiesBuilder<'a>

pub fn new(inherited: Option<&'a Arc<CustomPropertiesMap>>) -> Self

Create a new builder, inheriting from a given custom properties map.

pub fn cascade(
    &mut self,
    name: &'a Name,
    specified_value: DeclaredValue<'a, Arc<SpecifiedValue>>
)

Cascade a given custom property declaration.

pub fn build(self) -> Option<Arc<CustomPropertiesMap>>

Returns the final map of applicable custom properties.

If there was any specified property, we've created a new map and now we need to remove any potential cycles, and wrap it in an arc.

Otherwise, just use the inherited custom properties map.
