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) -> Self

The empty range.

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

pub fn select_all(galley: &Galley) -> Self

Select all the text in a galley

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 contains(&self, other: &Self) -> bool

Is self a super-set of the other range?

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

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

pub fn is_sorted(&self) -> bool

pub fn sorted(self) -> Self

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

Returns the two ends ordered.

pub fn slice_str<'s>(&self, text: &'s str) -> &'s str

pub fn on_key_press( &mut self, os: OperatingSystem, galley: &Galley, modifiers: &Modifiers, key: Key, ) -> bool

Check for key presses that are moving the cursor.

Returns true if we did mutate self.

pub fn on_event( &mut self, os: OperatingSystem, event: &Event, galley: &Galley, _widget_id: Id, ) -> bool

Check for events that modify the cursor range.

Returns true if such an event was found and handled.

Trait Implementations

impl Clone for CursorRange

fn clone(&self) -> CursorRange

Returns a copy 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

Formats the value using the given formatter.

impl Default for CursorRange

fn default() -> CursorRange

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CursorRange

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<CursorRange> for TextCursorState

fn from(cursor_range: CursorRange) -> Self

Converts to this type from the input 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 Serialize for CursorRange

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CursorRange
