Struct TextEdit 

pub struct TextEdit {
    pub range: Range<usize>,
    pub new_text: String,
    pub old_text: String,
}

A single atomic text edit expressed as a byte-range replacement.

Fields

range: Range<usize>

Byte range in the document before this edit is applied.

new_text: String

The text that replaces range.

old_text: String

The text that was present in range before the edit (stored so we can invert the operation for undo).

Implementations

impl TextEdit

pub fn new( range: Range<usize>, new_text: impl Into<String>, old_text: impl Into<String>, ) -> Self

Create a new edit.

pub fn inverse(&self) -> TextEdit

Return the inverse edit that undoes this one.

The inverse replaces the new_text (at the position it was inserted) with the original old_text.

Trait Implementations

impl Clone for TextEdit

fn clone(&self) -> TextEdit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextEdit

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

Formats the value using the given formatter.

impl PartialEq for TextEdit

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