Enum Delta 

pub enum Delta<T = Out> {
    Inserted(T, Option<Box<HashMap<Arc<str>, Any>>>),
    Deleted(u32),
    Retain(u32, Option<Box<HashMap<Arc<str>, Any>>>),
}

A single change done over a text-like types: Text or [XmlText].

Variants

Inserted(T, Option<Box<HashMap<Arc<str>, Any>>>)

Determines a change that resulted in insertion of a piece of text, which optionally could have been formatted with provided set of attributes.

Deleted(u32)

Determines a change that resulted in removing a consecutive range of characters.

Retain(u32, Option<Box<HashMap<Arc<str>, Any>>>)

Determines a number of consecutive unchanged characters. Used to recognize non-edited spaces between Delta::Inserted and/or Delta::Deleted chunks. Can contain an optional set of attributes, which have been used to format an existing piece of text.

Trait Implementations

impl<T> Clone for Delta<T>

where T: Clone,

fn clone(&self) -> Delta<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Delta<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> From<Diff<T>> for Delta

fn from(value: Diff<T>) -> Delta

Converts to this type from the input type.

impl<T> PartialEq for Delta<T>

where T: PartialEq,

fn eq(&self, other: &Delta<T>) -> 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.
