Struct ExtendReducer 

pub struct ExtendReducer;

Extend reducer - extends a list with items from another list

If the update is an array, all items are added to the current array. If the current value doesn’t exist or isn’t an array, creates a new array.

Example

// Before: { "items": [1, 2] }
// Update: { "items": [3, 4, 5] }
// After:  { "items": [1, 2, 3, 4, 5] }
