Struct GridSelection 

pub struct GridSelection<K> { /* private fields */ }

The selected rows or cells, by key. Cloning is O(1): the set is shared and copied on write.

Implementations

impl<K: Eq + Hash> GridSelection<K>

pub fn len(&self) -> usize

Rows with a selected row or at least one selected cell.

pub fn is_empty(&self) -> bool

Returns true if nothing is selected.

pub fn contains(&self, key: &K) -> bool

Returns true if the row is selected, or one of its cells is.

pub fn contains_cell(&self, key: &K, column: ColumnIx) -> bool

Returns true if the cell is selected; in the row modes, if its row is.

pub fn columns(&self, key: &K) -> ColumnSet

The selected columns of a row: every schema column in the row modes, ColumnSet::EMPTY if the row has nothing selected.

pub fn iter(&self) -> impl Iterator<Item = &K> + '_

The selected rows in no particular order.
