Types ¶

type Level ¶

type Level = slog.Level

type Logger ¶

type Logger struct {
	*slog.Logger
}

Logger wraps the slog.Logger type with support for a few additional levels

func Default ¶

func Default() *Logger

func GlobalLogger ¶ added in v0.19.3

func GlobalLogger(ctx context.Context, name string, attrs ...log.KeyValue) *Logger

GlobalLogger returns a Logger that sends logs to the global span, or the current span if none is configured.

func New ¶

func New(h slog.Handler) *Logger

func PrettyLogger ¶ added in v0.11.7

func PrettyLogger(dest io.Writer, profile termenv.Profile, level slog.Level) *Logger

func SpanLogger ¶ added in v0.11.7

func SpanLogger(ctx context.Context, name string, attrs ...log.KeyValue) *Logger

SpanLogger returns a Logger that writes to the give context's span logs.

The logger will use the context's baggage to determine the log level and color profile:

- If no-color=true is set in baggage, the profile will be Ascii. Otherwise, it will be ANSI.

- If debug=true is set in baggage, the log level will be Debug. Otherwise, it will be Info.

func With ¶

func With(args ...any) *Logger

func (*Logger) ExtraDebug ¶

func (l *Logger) ExtraDebug(msg string, args ...any)

func (*Logger) ExtraDebugContext ¶

func (l *Logger) ExtraDebugContext(ctx context.Context, msg string, args ...any)

func (*Logger) Trace ¶

func (l *Logger) Trace(msg string, args ...any)

func (*Logger) TraceContext ¶

func (l *Logger) TraceContext(ctx context.Context, msg string, args ...any)

func (*Logger) With ¶

func (l *Logger) With(args ...any) *Logger
