Häufige Annahme

Passing multiple cmp.Transformer or cmp.Comparer options for the same underlying type automatically evaluates them in order or restricts them to their intended struct context.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• assert cmp.Diff panics with ambiguous set of applicable options when multiple transformers or comparers target the same type without path filters
• assert grouping conflicting transformers inside a cmp.Options slice does not bypass option ambiguity
• assert cmp.Comparer and cmp.Transformer panic at construction time when provided invalid function signatures
• assert cmp.FilterPath successfully scopes field transformations to specific struct paths without triggering ambiguity panics
• assert overlapping cmp.FilterPath predicates matching the same path panic at comparison time
