常见的想当然

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.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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
