CalcUnits

Expected units we allow parsing within a calc() expression.

GenericAnchorFunctionFallback

Fallback type for anchor functions within calc(). Ideally, the fallback type is initial type of the property (e.g. GenericInset for left), but that causes circular reference. TODO(dshin, bug 2034100): Investigate ways to not require this. This handles the parsing of unitless zeros, as well as ensuring that e.g. calc(anchor(--foo left, 1px) + 10%) round trips (sorting aside), instead of becoming calc(anchor(--foo left, calc(1px)) + 10%).

Enums

ArgumentLevel 🔒

The level of any argument being serialized in to_css_impl.

GenericCalcNode

A generic node in a calc expression.

MinMaxOp

Whether we’re a min or max function.

ModRemOp

Whether we’re a mod or rem function.

PositivePercentageBasis

For percentage resolution, sometimes we can’t assume that the percentage basis is positive (so we don’t know whether a percentage is larger than another).

RoundingStrategy

The strategy used in round()

SortKey

This determines the order in which we serialize members of a calc() sum.

Traits

CalcNodeLeaf

A trait that represents all the stuff a valid leaf of a calc expression.

Type Aliases

GenericCalcAnchorFunction

anchor() function used in math functions.

GenericCalcAnchorSizeFunction

anchor-size() function used in math functions.
