Trait LayoutMerge 

pub trait LayoutMerge: 'static {
    // Required method
    fn merge(
        &self,
        context: &LayoutMergeContext<'_>,
        saved: &GridLayout,
    ) -> Vec<LayoutColumn>;
}

Resolves a saved layout against the current schema. Called once per import.

The default is AppendNewColumns. An alternative could place a new column next to its neighbour in the schema, or keep unknown columns for a schema that depends on the user’s permissions.

Required Methods

fn merge( &self, context: &LayoutMergeContext<'_>, saved: &GridLayout, ) -> Vec<LayoutColumn>

One entry per schema column, in display order. The grid validates the result whatever the implementation returns: it adds missing columns, drops unknown ones and repeats, clamps widths, splits the order by zone and keeps one column visible.
