Struct style::properties::generated::ComputedValues

pub struct ComputedValues {
    inner: ComputedValuesInner,
    pseudo: Option<PseudoElement>,
}

The struct that Servo uses to represent computed values.

This struct contains an immutable atomically-reference-counted pointer to every kind of style struct.

When needed, the structs may be copied in order to get mutated.

Fields

inner: ComputedValuesInner

The actual computed values

In Gecko the outer ComputedValues is actually a ComputedStyle, whereas ComputedValuesInner is the core set of computed values.

We maintain this distinction in servo to reduce the amount of special casing.

pseudo: Option<PseudoElement>

The pseudo-element that we’re using.
