The implemention of the interface in this project includes the interface itself

[xtudouh]

type Logger interface {
Level() levels.LogLevel
Name() string
FullName() string
...
}
type logger struct {
Logger
level levels.LogLevel
name string
enabled map[levels.LogLevel]bool
appender Appender
children []Logger
parent Logger
ExitOnFatal bool
}
In the type logger, Logger is if unnecessary or not.
