pub struct CursorRange {
    pub primary: Cursor,
    pub secondary: Cursor,
}
Expand description

A selected text range (could be a range of length zero).

Fields§

§primary: Cursor

When selecting with a mouse, this is where the mouse was released. When moving with e.g. shift+arrows, this is what moves. Note that the two ends can come in any order, and also be equal (no selection).

§secondary: Cursor

When selecting with a mouse, this is where the mouse was first pressed. This part of the cursor does not move when shift is down.

Implementations§

source§

impl CursorRange

source

pub fn one(cursor: Cursor) -> Self

The empty range.

source

pub fn two(min: Cursor, max: Cursor) -> Self

source

pub fn as_ccursor_range(&self) -> CCursorRange

source

pub fn as_sorted_char_range(&self) -> Range<usize>

The range of selected character indices.

source

pub fn is_empty(&self) -> bool

True if the selected range contains no characters.

source

pub fn single(&self) -> Option<Cursor>

If there is a selection, None is returned. If the two ends is the same, that is returned.

source

pub fn is_sorted(&self) -> bool

source

pub fn sorted(self) -> Self

source

pub fn sorted_cursors(&self) -> [Cursor; 2]

returns the two ends ordered
