Implementations

impl Sizes

pub(crate) fn new(preferred: Size<Au>, min: Size<Au>, max: Size<Au>) -> Self

pub(crate) fn depends_on_available_space(&self) -> bool

pub(crate) fn resolve( &self, automatic_size: Size<Au>, automatic_minimum_size: Au, stretch_size: Au, get_content_size: impl FnOnce() -> ContentSizes, ) -> Au

Resolves the three sizes into a single numerical value.

pub(crate) fn resolve_each( &self, automatic_size: Size<Au>, automatic_minimum_size: Au, stretch_size: Au, get_content_size: impl FnOnce() -> ContentSizes, ) -> (Au, Au, Option<Au>)

Resolves each of the three sizes into a numerical value, separately.

pub(crate) fn resolve_extrinsic( &self, automatic_size: Size<Au>, automatic_minimum_size: Au, stretch_size: Option<Au>, ) -> SizeConstraint

Tries to extrinsically resolve the three sizes into a single SizeConstraint. Values that are intrinsic or need stretch_size when it’s None are handled as such:

• On the preferred size, they make the returned value be an indefinite SizeConstraint::MinMax.
• On the min size, they are treated as auto, enforcing the automatic minimum size.
• On the max size, they are treated as none, enforcing no maximum.

pub(crate) fn resolve_each_extrinsic( &self, automatic_size: Size<Au>, automatic_minimum_size: Au, stretch_size: Option<Au>, ) -> (Option<Au>, Au, Option<Au>)

Tries to extrinsically resolve each of the three sizes into a numerical value, separately. This can’t resolve values that are intrinsic or need stretch_size but it’s None.

• The 1st returned value is the resolved preferred size. If it can’t be resolved then the returned value is None. Note that this is different than treating it as auto. TODO: This needs to be discussed in https://github.com/w3c/csswg-drafts/issues/11387.
• The 2nd returned value is the resolved minimum size. If it can’t be resolved then we treat it as the initial auto, returning the automatic minimum size.
• The 3rd returned value is the resolved maximum size. If it can’t be resolved then we treat it as the initial none, returning None.
