Struct Selection 

pub struct Selection {
    pub scope: Key,
    pub anchor: Endpoint,
    pub focus: Endpoint,
}

The window’s selection: a scope and two ends of it. anchor is where the press landed and focus is where the pointer is now, so the pair is directed — dragging back past the anchor selects the other way without the two swapping, which is what keeps a drag from feeling like it jumps when it crosses its own start.

Fields

scope: Key

The selectable node the selection lives inside.

anchor: Endpoint

focus: Endpoint

Implementations

impl Selection

pub fn new(scope: Key, anchor: Endpoint, focus: Endpoint) -> Self

pub fn is_empty(&self) -> bool

A selection of no text — a click that placed both ends together. It still exists (the scope is where the next Shift-click or drag extends from), and it copies nothing.
