Module: Errgonomic::OptionalDig

Included in:

OptionalArray, OptionalHash

Defined in:

lib/errgonomic/optional_dig.rb

Overview

The presence-checking walk behind OptionalHash#dig and OptionalArray#dig: every step checks key or bounds presence, so an absent path (None) stays distinct from a present nil (Some(nil)), which the core dig methods conflate. A nested wrapper handles the rest of the walk itself, by recursion. Digging into a non-collection raises, pedantically, where core dig would raise TypeError.
