Implementations

impl<'a> AbsoluteAxisSolver<'a>

fn inset_sum(&self) -> Au

Returns the amount that we need to subtract from the containing block size in order to obtain the inset-modified containing block that we will use for sizing purposes. (Note that for alignment purposes, we may re-resolve auto insets to a different value.) https://drafts.csswg.org/css-position/#resolving-insets

fn solve( &self, get_content_size: Option<impl FnOnce() -> ContentSizes>, ) -> AxisResult

This unifies some of the parts in common in:

• https://drafts.csswg.org/css2/visudet.html#abs-non-replaced-width
• https://drafts.csswg.org/css2/visudet.html#abs-non-replaced-height

… and:

• https://drafts.csswg.org/css2/visudet.html#abs-replaced-width
• https://drafts.csswg.org/css2/visudet.html#abs-replaced-height

In the replaced case, size is never Auto.
