Struct style::properties_and_values::registry::PropertyRegistration

pub struct PropertyRegistration {
    pub name: PropertyRuleName,
    pub data: PropertyRegistrationData,
    pub url_data: UrlExtraData,
    pub source_location: SourceLocation,
}

A computed, already-validated property registration. https://drafts.css-houdini.org/css-properties-values-api-1/#custom-property-registration

Fields

name: PropertyRuleName

The custom property name.

data: PropertyRegistrationData

The actual information about the property.

url_data: UrlExtraData

The url data that is used to parse and compute the registration’s initial value. Note that it’s not the url data that should be used to parse other values. Other values should use the data of the style sheet where they came from.

source_location: SourceLocation

The source location of this registration, if it comes from a CSS rule.
