Struct Edit 

pub struct Edit {
    pub at: usize,
    pub removed: usize,
    pub inserted: String,
}

A splice to apply to the buffer, in byte offsets over the pre-edit text: at..at+removed is replaced by inserted. Edit::apply applies it to a String mirror; Edit::splice_automerge to a char-addressed Automerge Text.

Fields

at: usize

removed: usize

inserted: String

Implementations

impl Edit

pub fn is_noop(&self) -> bool

Whether nothing changed (no delete, no insert).

pub fn caret_after(&self) -> usize

New byte caret position after this edit is applied.

pub fn range(&self) -> Range<usize>

The replaced byte range in the pre-edit text.

pub fn char_splice(&self, before: &str) -> Option<CharSplice>

The same splice in char offsets over before (the pre-edit text). None when the byte range does not land on before’s char boundaries — the edit was computed against different text.

pub fn apply(&self, text: &mut String) -> bool

Apply the splice to text. Returns false (leaving text untouched) when the range does not land on char boundaries.

pub fn splice_automerge<T>( &self, doc: &mut T, obj: &ExId, before: &str, ) -> Option<CharSplice>

where T: Transactable,

Splice the edit into the Automerge Text obj, whose current content is before. Returns the char-space splice so a caller can stamp marks over the inserted run, or None when the edit does not fit before.

Trait Implementations

impl Clone for Edit

fn clone(&self) -> Edit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Edit

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

Formats the value using the given formatter.

impl Default for Edit

fn default() -> Edit

Returns the “default value” for a type.

impl PartialEq for Edit

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