Struct mz_expr::explain::text::FmtNode

struct FmtNode<F, G>
where
    F: FnOnce(&mut Formatter<'_>, &mut PlanRenderingContext<'_, MirRelationExpr>) -> Result,
    G: FnOnce(&mut Formatter<'_>, &mut PlanRenderingContext<'_, MirRelationExpr>) -> Result,
{
    fmt_root: F,
    fmt_children: G,
}

A helper struct that abstracts over the formatting behavior of a single-input node.

If mz_repr::explain::ExplainConfig::linear_chains is set, this will render children before parents using the same indentation level, and if not the children will be rendered indented after their parent.

Fields

fmt_root: F

fmt_children: G
