Struct loro_delta::DeltaRope

pub struct DeltaRope<V: DeltaValue, Attr: DeltaAttr> { /* private fields */ }

A DeltaRope is a rope-like data structure that can be used to represent a sequence of DeltaItem. It has efficient operations for composing other DeltaRopes. It can also be used as a rope, where it only contains insertions.

Implementations

impl<V: Debug + Clone, const C: usize, Attr: DeltaAttr> DeltaRope<ArrayVec<V, C>, Attr>

pub fn from_many(iter: impl Iterator<Item = V>) -> Self

impl<V: DeltaValue, Attr: DeltaAttr> DeltaRope<V, Attr>

pub fn compose(&mut self, other: &Self)

impl<V: DeltaValue, Attr: DeltaAttr> DeltaRope<V, Attr>

pub fn new() -> Self

pub fn first(&self) -> Option<&DeltaItem<V, Attr>>

pub fn iter(&self) -> impl Iterator<Item = &DeltaItem<V, Attr>>

pub fn len(&self) -> usize

Returns the length of the delta rope (insertions + retains).

pub fn old_len(&self) -> usize

Returns the length of the delta rope (deletions + retains).

pub fn is_empty(&self) -> bool

pub fn push_insert(&mut self, v: V, attr: Attr) -> &mut Self

pub fn push_retain(&mut self, retain: usize, attr: Attr) -> &mut Self

pub fn push_replace(&mut self, value: V, attr: Attr, delete: usize) -> &mut Self

pub fn push_delete(&mut self, len: usize) -> &mut Self

pub fn push(&mut self, item: DeltaItem<V, Attr>) -> &mut Self

pub fn iter_with_len(&self) -> Iter<'_, V, Attr>

Returns an iterator that can iterate over the delta rope with a custom length.

It’s more controllable compared to the default iterator.

• Iterating over the delta rope with a custom length.
• You can peek the next item.

It’s useful to implement algorithms related to Delta

pub fn chop(&mut self)

impl<Attr: DeltaAttr> DeltaRope<TextChunk, Attr>

pub fn insert_str(&mut self, index: usize, s: &str)

pub fn push_str_insert(&mut self, s: &str) -> &mut Self

pub fn push_str_insert_with_attr(&mut self, s: &str, attr: Attr) -> &mut Self

pub fn try_to_string(&self) -> Option<String>

Trait Implementations

impl<V: Clone + DeltaValue, Attr: Clone + DeltaAttr> Clone for DeltaRope<V, Attr>

fn clone(&self) -> DeltaRope<V, Attr>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: DeltaValue, Attr: DeltaAttr> Debug for DeltaRope<V, Attr>

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

Formats the value using the given formatter.

impl<V: DeltaValue + Debug, Attr: DeltaAttr + Debug> Default for DeltaRope<V, Attr>

fn default() -> Self

Returns the “default value” for a type.

impl<V: DeltaValue + PartialEq, Attr: DeltaAttr + PartialEq> PartialEq for DeltaRope<V, Attr>

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
