Method UnmarshalText

zapcore/level.go:170–178

UnmarshalText unmarshals text to a level. Like MarshalText, UnmarshalText expects the text representation of a Level to drop the -Level suffix (see example). In particular, this makes it easy to configure logging levels using YAML, TOML, or JSON files.
