Enum EditOperation 

pub enum EditOperation {
    Insert {
        pos: CursorPosition,
        text: String,
    },
    Delete {
        pos: CursorPosition,
        text: String,
    },
    Replace {
        pos: CursorPosition,
        old_text: String,
        new_text: String,
    },
}

A single text editing operation that can be undone and redone.

Variants

Insert

Text was inserted at a position.

Fields

pos: CursorPosition

Position where text was inserted.

text: String

The text that was inserted.

Delete

Text was deleted from a position.

Fields

pos: CursorPosition

Position where text was deleted.

text: String

The text that was deleted.

Replace

Text was replaced at a position.

Fields

pos: CursorPosition

Position where replacement started.

old_text: String

The old text that was replaced.

new_text: String

The new text that replaced it.

Implementations

impl EditOperation

pub fn inverse(&self) -> Self

Return the inverse of this operation.

Applying the inverse undoes the original operation:

• Insert → Delete (and vice versa)
• Replace swaps old_text and new_text

Trait Implementations

impl Clone for EditOperation

fn clone(&self) -> EditOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EditOperation

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

Formats the value using the given formatter.

impl PartialEq for EditOperation

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