Why is this zerolog hook an ineffective assignment?
问题
我想将zerolog的消息存储在一个切片中，以便轻松访问最后的n条消息。memoryLog.messages保持为null，并且golangci-lint报告了ineffective assignment to field memoryLog.messages的问题。我对Go还很陌生，感觉好像漏掉了一些明显的东西，但我就是找不出来。
type memoryLog struct {
config config
messages []string
}
func (memoryLog memoryLog) Run(event *zerolog.Event, level zerolog.Level, message string) {
memoryLog.messages = append([]string{message}, memoryLog.messages...)
if len(memoryLog.messages) > memoryLog.config.MemoryLogMaxItems {
memoryLog.messages = memoryLog.messages[:memoryLog.config.MemoryLogMaxItems]
}
}
memoryLog := memoryLog{config: config}
logger := log.Hook(memoryLog)
英文:
I want to store zerolog messages in a slice for easy access to the last n messages. memoryLog.messages stays null and golangci-lint complains about ineffective assignment to field memoryLog.messages. I'm still new to Go and it feels like I'm missing something obvious, but I just can't figure it out.
type memoryLog struct {
config config
messages []string
}
func (memoryLog memoryLog) Run(event *zerolog.Event, level zerolog.Level, message string) {
memoryLog.messages = append([]string{message}, memoryLog.messages...)
if len(memoryLog.messages) > memoryLog.config.MemoryLogMaxItems {
memoryLog.messages = memoryLog.messages[:memoryLog.config.MemoryLogMaxItems]
}
}
memoryLog := memoryLog{config: config}
logger := log.Hook(memoryLog)

感谢我得到的帮助，它正在工作：
func (log *memoryLog) Run(event *zerolog.Event, level zerolog.Level, message string) {
//...
}
logger := log.Hook(&memoryLog)

Thanks to the help I got it working:
func (log *memoryLog) Run(event *zerolog.Event, level zerolog.Level, message string) {
//...
}
logger := log.Hook(&memoryLog)
