Enum GridTarget 

#[non_exhaustive]
pub enum GridTarget<K, C> {
    Cell {
        key: K,
        column: C,
    },
    Pinned {
        edge: PinnedEdge,

}

What a press or the keyboard pointed at. Captured when the button goes down, so a re-sort before the menu is built cannot retarget it.

A value type: its variants’ fields are its definition.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cell

A data cell.

Fields

key: K

The row.

column: C

The column.

Pinned

A cell of a pinned row. Its key is of its band’s own key space: a data row or the other band may have the same key.

Fields

edge: PinnedEdge

The band.

key: K

The pinned row.

column: C

The column.

Header

A column header cell, a band (its first visible column) or a resize handle.

Fields

column: C

The column.

Empty

The body or header outside rows and columns; the keyboard menu with no focused cell.

GroupCaption

A group caption.

Fields

group: GroupPath

The group.

column: Option<C>

The aggregate cell under the pointer, if any; None from the keyboard.

GroupFooter

A cell of a group footer.

Fields

group: GroupPath

The group the footer sums up.

column: C

The column.

Totals

A cell of the totals row.

Fields

edge: PinnedEdge

The band the totals row is in.

column: C

The column.

Implementations

impl<K, C: Copy> GridTarget<K, C>

pub fn key(&self) -> Option<&K>

The data row key of a cell target. A pinned row’s key is of its band’s key space, so it is not returned here, where it could be taken for a data row’s (match GridTarget::Pinned).

pub fn column(&self) -> Option<C>

The column of a cell, pinned cell, header, footer or totals target, and of a caption’s aggregate cell.

pub fn group(&self) -> Option<&GroupPath>

The group of a caption or footer target.

Trait Implementations

impl<K: Clone, C: Clone> Clone for GridTarget<K, C>

fn clone(&self) -> GridTarget<K, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, C: Debug> Debug for GridTarget<K, C>

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

Formats the value using the given formatter.

impl<K: PartialEq, C: PartialEq> PartialEq for GridTarget<K, C>

fn eq(&self, other: &GridTarget<K, C>) -> 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.
