Enum SelectionEdit 

#[non_exhaustive]
pub enum SelectionEdit {
    Replace,
    Extend,
    AddRange,
    Toggle,
    Keep,
}

How a gesture changes the selection; the target always gets the focus.

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.

Replace

Select only the target; it becomes the anchor.

Extend

Select the range from the anchor to the target, dropping the rest.

AddRange

Add the range from the anchor to the target to the selection.

Toggle

Flip the target; it becomes the anchor.

Keep

Leave the selection and the anchor as they are.
