Actions for manipulating text selections.

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.

Duplicate(MoveDir1D, Count)

Duplicate selections n times to adjacent lines in MoveDir1D direction.

If the column positions are too large to fit on the adjacent lines, then the next line large enough to hold the selection is used instead.

CursorSet(SelectionCursorChange)

Change the placement of the cursor and anchor of a visual selection.

Expand(SelectionBoundary, TargetShapeFilter)

Expand a selection by repositioning its cursor and anchor such that they are placed on the specified boundary.

Be aware that since this repositions the start and end of the selection, this may not do what you want with TargetShape::BlockWise selections.

Filter(bool)

Filter selections using the last regular expression entered for CommandType::Search.

The bool argument indicates whether we should drop selections that match instead of keeping them.

Join

Join adjacent selections together.

Resize(SelectionResizeStyle, EditTarget)

Change the bounds of the current selection as described by the style and target.

If the context doesn’t specify a selection shape, then the selection will determine its shape from the EditTarget.

Split(SelectionSplitStyle, TargetShapeFilter)

Split matching selections into multiple selections line.

All of the new selections are of the same shape as the one they were split from.

Trim(SelectionBoundary, TargetShapeFilter)

Shrink a selection by repositioning its cursor and anchor such that they are placed on the specified boundary.

Be aware that since this repositions the start and end of the selection, this may not do what you want with TargetShape::BlockWise selections.

Trait Implementations

impl Clone for SelectionAction

fn clone(&self) -> SelectionAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionAction

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

Formats the value using the given formatter.

impl<I: ApplicationInfo> From<SelectionAction> for Action<I>

fn from(act: SelectionAction) -> Self

Converts to this type from the input type.

impl From<SelectionAction> for EditorAction

fn from(act: SelectionAction) -> Self

Converts to this type from the input type.

impl PartialEq for SelectionAction

fn eq(&self, other: &SelectionAction) -> 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.
