Implementations

impl<Value, Meta> DeltaItem<Value, Meta>

pub fn is_retain(&self) -> bool

Returns true if this is a DeltaItem::Retain, otherwise false

pub fn as_retain_mut(&mut self) -> Option<(&mut usize, &mut Meta)>

Optionally returns mutable references to the inner fields if this is a DeltaItem::Retain, otherwise None

Trait Implementations

impl<Value: Clone, Meta: Clone> Clone for DeltaItem<Value, Meta>

fn clone(&self) -> DeltaItem<Value, Meta>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Value: Debug, Meta: Debug> Debug for DeltaItem<Value, Meta>

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

Formats the value using the given formatter.

impl<V: DeltaValue, M: Debug> DeltaValue for DeltaItem<V, M>

fn value_extend(&mut self, _other: Self) -> Result<(), Self>

the other will be merged into self

fn take(&mut self, _length: usize) -> Self

takes the first number of length elements

fn length(&self) -> usize

the length of the value

impl From<&DeltaItem<StringSlice, StyleMeta>> for TextDelta

fn from(value: &DeltaItem<StringSlice, StyleMeta>) -> Self

Converts to this type from the input type.

impl<Value: PartialEq, Meta: PartialEq> PartialEq for DeltaItem<Value, Meta>

fn eq(&self, other: &DeltaItem<Value, Meta>) -> 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.

where Value: Serialize, Meta: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

fn to_json(&self) -> String

fn to_json_pretty(&self) -> String
