var Levels = struct {
	INFO, DEBUG, WARN, ERROR Level
}{
	INFO:  Level(slog.LevelInfo),
	DEBUG: Level(slog.LevelDebug),
	WARN:  Level(slog.LevelWarn),
	ERROR: Level(slog.LevelError),
}

Levels are a simple abstractions on slog.Level.

Functions ¶

func GetLogTraceback ¶

func GetLogTraceback(skipLevel int) string

GetLogTraceback return a string with info about filename, function name and line https://stackoverflow.com/questions/25927660/how-to-get-the-current-function-name

func LogError ¶ added in v1.0.5

func LogError(logger Logger, msg string, err error, args ...any)

LogError logs error with message info, using provided logger.

func LogErrorContext ¶ added in v1.0.5

func LogErrorContext(ctx context.Context, logger Logger, msg string, err error, args ...any)

LogErrorContext uses provided logger to save error with message info and context. Context is used to get request ID and connect it with error.

func LogInfo ¶ added in v1.0.9

func LogInfo(logger Logger, msg string, args ...any)

LogInfo logs message, using provided logger.

func LogInfoContext ¶ added in v1.6.0

LogInfoContext uses provided logger to save message info and context. Context is used to get request ID and connect it with error.

Types ¶

type Config ¶

type Config struct {
	Level       Level
	LogFilePath string
}

Config is a logging config, on base of which logger instance is created.

type Level ¶ added in v1.5.0

type Level int

type Logger ¶ added in v1.5.0

type Logger interface {
	Debug(msg string, args ...any)
	DebugContext(ctx context.Context, msg string, args ...any)
	Info(msg string, args ...any)
	InfoContext(ctx context.Context, msg string, args ...any)
	Warn(msg string, args ...any)
	WarnContext(ctx context.Context, msg string, args ...any)
	Error(msg string, args ...any)
	ErrorContext(ctx context.Context, msg string, args ...any)
}

Logger interface is created for usage in external application according to "dependency inversion principle" of SOLID due to working via abstractions.

func New ¶ added in v1.5.1

func New(logLevel Level, logFilePath string) Logger
