Struct TextSelection 

pub struct TextSelection {
    pub start: usize,
    pub end: usize,
}

Text selection range.

Fields

start: usize

Selection start (byte offset)

end: usize

Selection end (byte offset)

Implementations

impl TextSelection

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

Create a new selection.

pub fn range(&self) -> (usize, usize)

Get the selection as (min, max) to ensure start <= end.

pub fn len(&self) -> usize

Get the selection length in bytes.

pub fn is_empty(&self) -> bool

Check if the selection is empty.

pub fn contains(&self, position: usize) -> bool

Check if the selection contains a byte position.

Trait Implementations

impl Clone for TextSelection

fn clone(&self) -> TextSelection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextSelection

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

Formats the value using the given formatter.

impl PartialEq for TextSelection

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