Struct CursorRange

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

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

impl CursorRange

pub fn one(cursor: Cursor) -> CursorRange

The empty range.

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

pub fn as_ccursor_range(&self) -> CCursorRange

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

The range of selected character indices.

pub fn is_empty(&self) -> bool

True if the selected range contains no characters.

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

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

pub fn is_sorted(&self) -> bool

pub fn sorted(self) -> CursorRange

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

returns the two ends ordered

Trait Implementations

impl Clone for CursorRange

fn clone(&self) -> CursorRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CursorRange

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

Formats the value using the given formatter.

impl Default for CursorRange

fn default() -> CursorRange

Returns the “default value” for a type.

impl PartialEq for CursorRange

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

impl Copy for CursorRange

impl StructuralPartialEq for CursorRange
