Struct Undo 

pub struct Undo;

Built-in action to trigger an undo operation.

Applications that support undo/redo should register a reducer for this action on their state type.

Trait Implementations

impl Action for Undo

fn static_id() -> ActionId

Returns the globally unique, deterministic identifier for this action type.

fn encode(&self) -> Vec<u8>

Serialises the action to JSON bytes for transport inside an ActionEnvelope.

impl Clone for Undo

fn clone(&self) -> Undo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Undo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Undo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Undo

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

impl Serialize for Undo

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Undo

impl StructuralPartialEq for Undo
