Enum SelectionMode 

pub enum SelectionMode {
    Replace,
    Toggle,
    ExtendRange,
}

How a click or keyboard gesture modifies the selection set.

Modifier-key mapping (Ctrl → Toggle, Shift → ExtendRange) is handled by the component layer (RFC 006) because keyboard modifiers arrive on the event object, not in widget state.

Variants

Replace

Clear the selection and select only this path.

Clicking an already-selected row still results in exactly that one row selected (S3.4 — no implicit deselect-on-re-click).

Toggle

Add if absent; remove if already selected. Updates the anchor.

ExtendRange

Select the contiguous range from the current anchor to this path in crate::DirectoryTree::visible_rows order.

If no anchor is set, behaves as SelectionMode::Replace. The anchor does not move (S6.3): repeated Shift-clicks grow or shrink the range from the same pivot.

Trait Implementations

impl Clone for SelectionMode

fn clone(&self) -> SelectionMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SelectionMode

impl Debug for SelectionMode

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

Formats the value using the given formatter.

impl Eq for SelectionMode

impl PartialEq for SelectionMode

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