Module: Plushie::Model

Defined in:
lib/plushie/model.rb,
sig/plushie/model.rbs

Overview

Convenience wrapper around Data.define that adds a #with method for partial updates, producing a new immutable instance.

Model = Plushie::Model.define(:count, :name)
m = Model.new(count: 0, name: "test")
m.with(count: 1) # => Model(count: 1, name: "test")

Instances are frozen by default (inherited from Data). Attempting to mutate raises FrozenError.
