This package is designed for low level libraries to optimize reflection performance. General application should still use reflect standard library. reflect2.TypeByName reflect2 get/set interface{} to get set type , always use its pointer type reflect2 get/set unsafe.Pointer to get set type , always use its pointer type benchmark Benchmark is not necessary for this package. It does nothing actually. As it is just a thin wrapper to make go runtime public. Both reflect2 and reflect call same function provided by runtime package exposed by go language. unsafe safety Instead of casting []byte to sliceHeader in your application using unsafe. We can use reflect2 instead. This way, if sliceHeader changes in the future, only reflect2 need to be upgraded. reflect2 tries its best to keep the implementation same as reflect (by testing).","default_branch":null,"files":null,"tree":[],"storefront":"/r/modern-go","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/modern-go/reflect2/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
