Enum ApproxLayout

enum ApproxLayout {
    Inline {
        worst_width: Columns,
        excess_width_from_only_if_block: Columns,
    },
    BlockOrMixed {
        pre_worst_width: Columns,
        post_worst_width: Columns,
    },
}

The approximate shape of a Node, regarding its 2D placement.

Variants

Inline

Only occupies part of a line, (at most) worst_width columns wide.

worst_width can exceed the inline field of MaxWidths, in which case the choice of inline vs block is instead made by a surrounding node.

Fields

worst_width: Columns

excess_width_from_only_if_block: Columns

How much of worst_width comes from Node::IfBlockLayout - that is, worst_width still includes Node::IfBlockLayout, so conservative decisions will still be made, but excess_width_from_only_if_block can be used to reduce worst_width when block layout is no longer a possibility (i.e. by the enclosing Node::InlineOrIndentedBlock).

BlockOrMixed

Needs to occupy multiple lines, but may also have the equivalent of an Inline before (pre_) and after (post_) the multi-line block.

Fields

pre_worst_width: Columns

post_worst_width: Columns
