Struct Selection 

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

Available on crate feature editor only.

A text selection range in the document.

Fields

start: CursorPosition

Start position of the selection

end: CursorPosition

End position of the selection

Implementations

impl Selection

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

Create a new selection range.

pub const fn empty(position: CursorPosition) -> Self

Create an empty selection at a position.

pub fn is_empty(&self) -> bool

Check if the selection is empty (no text selected).

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

Check if a position is within this selection.

pub fn normalized(&self) -> (CursorPosition, CursorPosition)

Get normalized start and end (start is always before end).

pub fn overlaps(&self, other: &Self) -> bool

Check if this selection overlaps with another.

pub fn merge(&self, other: &Self) -> Option<Self>

Merge this selection with another (if they overlap or are adjacent).

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<'de> Deserialize<'de> for Selection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for Selection

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 Selection

impl Eq for Selection

impl StructuralPartialEq for Selection
