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)

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