Module: T::Props::HasLazilySpecializedMethods

Extended by:
Sig
Defined in:
lib/types/props/has_lazily_specialized_methods.rb

Overview

Helper for generating methods that replace themselves with a specialized version on first use. The main use case is when we want to generate a method using the full set of props on a class; we can’t do that during prop definition because we have no way of knowing whether we are defining the last prop.

See go/M8yrvzX2 (Stripe-internal) for discussion of security considerations. In outline, while ‘class_eval` is a bit scary, we believe that as long as all inputs are defined in version control (and this is enforced by calling `disable_lazy_evaluation!` appropriately), risk isn’t significantly higher than with build-time codegen.
