Struct druid::text::selection::Selection

pub struct Selection {
    pub start: usize,
    pub end: usize,
    pub h_pos: Option<f64>,
}

A Selection type for EditableText.

Fields

start: usize

The inactive edge of a selection, as a byte offset. When equal to end, the selection range acts as a caret.

end: usize

The active edge of a selection, as a byte offset.

h_pos: Option<f64>

The saved horizontal position, during vertical movement.

Implementations

impl Selection

pub fn new(start: usize, end: usize) -> Self

Create a selection that begins at start and goes to end. Like dragging a mouse from start to end.

#[must_use = "constrained constructs a new Selection"]pub fn constrained(self, s: &impl EditableText) -> Self

Create a new selection that is guaranteed to be valid for the provided text.

pub fn caret(pos: usize) -> Self

Create a caret, which is just a selection with the same and start and end.

pub fn with_h_pos(self, h_pos: Option<f64>) -> Self

Construct a new selection from this selection, with the provided h_pos.

pub fn is_caret(self) -> bool

If start == end, it's a caret

pub fn min(self) -> usize

Return the smallest index (left, in left-to-right languages)

pub fn max(self) -> usize

Return the largest index (right, in left-to-right languages)

pub fn range(self) -> Range<usize>

Return a range from smallest to largest index

Trait Implementations

impl Clone for Selection

pub fn clone(&self) -> Selection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Selection

impl Debug for Selection

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

Formats the value using the given formatter.
