func Adapt ¶
Adapt performs intelligent conversion from Kratos error to standard error interface Solves Go's core nil interface problem where (*T)(nil) != nil Returns true nil when given nil pointers to prevent interface pollution Essential when working with packages expecting clean error interface semantics
Reference: https://go.dev/doc/faq#nil_error Technical Details: - Go interfaces are (type, value) pairs where both must be nil for interface to be nil - (*errors.Error)(nil) creates interface with (concrete type, nil value) != nil - This function ensures correct nil interface creation for safe error handling
Adapt 执行从 Kratos 错误到标准错误接口的智能转换 解决 Go 的核心 nil 接口问题，其中 (*T)(nil) != nil 在给定 nil 指针时返回真正的 nil，防止接口污染 在使用期望干净错误接口语义的包时至关重要
参考: https://go.dev/doc/faq#nil_error 技术细节: - Go 接口是 (类型, 值) 对，两者都必须为 nil 接口才为 nil - (*errors.Error)(nil) 创建具有 (具体类型, nil 值) 的接口 != nil - 此函数确保正确的 nil 接口创建以进行安全错误处理
