Struct Selection 

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

A selection in the text, represented by start and end byte indices.

Fields

start: usize

end: usize

Implementations

impl Selection

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

Clears the selection, setting start and end to 0.

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

Checks if the given offset is within the selection range.

Trait Implementations

impl Clone for Selection

fn clone(&self) -> Selection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selection

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

Formats the value using the given formatter.

impl Default for Selection

fn default() -> Selection

Returns the “default value” for a type.

impl From<Range<usize>> for Selection

fn from(value: Range<usize>) -> Self

Converts to this type from the input type.

impl From<Selection> for Range<usize>

fn from(value: Selection) -> Self

Converts to this type from the input type.

impl PartialEq for Selection

fn eq(&self, other: &Selection) -> 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 RangeBounds<usize> for Selection

fn start_bound(&self) -> Bound<&usize>

Start index bound.

fn end_bound(&self) -> Bound<&usize>

End index bound.

fn contains<U>(&self, item: &U) -> bool

where T: PartialOrd<U>, U: PartialOrd<T> + ?Sized,

Returns true if item is contained in the range.

fn is_empty(&self) -> bool

where T: PartialOrd,

🔬This is a nightly-only experimental API. (range_bounds_is_empty)

Returns true if the range contains no items. One-sided ranges (RangeFrom, etc) always return false.
