Struct LayoutReport 

pub struct LayoutReport { /* private fields */ }

What applying a saved layout had to adjust to fit the current schema.

The grid computes it from the schema and the saved layout, whatever the LayoutMerge returns.

Implementations

impl LayoutReport

pub fn ignored_columns(&self) -> &[ColumnId]

Saved columns that the schema no longer has; ignored.

pub fn added_columns(&self) -> &[ColumnId]

Schema columns the layout did not have; added with schema defaults.

pub fn dropped_sort(&self) -> &[ColumnId]

Sort keys on unknown columns and repeated keys; dropped.

pub fn dropped_group_by(&self) -> &[ColumnId]

Grouping levels on columns the schema does not have or cannot group, and repeated levels; dropped, and the levels below move up. In saved order, each id once. A column can be in Self::dropped_sort too.

pub fn dropped_expansion(&self) -> usize

The number of saved toggled groups that do not fit the restored grouping: empty, deeper than its levels, or with a value this build cannot hold; dropped.

pub fn is_exact(&self) -> bool

Returns true if every saved column, sort key, grouping level and toggled group matched the schema and every schema column was saved. Widths clamped to a column’s limits do not count as adjustments.

Trait Implementations

impl Clone for LayoutReport

fn clone(&self) -> LayoutReport

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LayoutReport

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LayoutReport

fn default() -> LayoutReport

Returns the “default value” for a type.

impl PartialEq for LayoutReport

fn eq(&self, other: &LayoutReport) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
