Types

type HandlerFn

type HandlerFn func(slog.Handler) slog.Handler

HandlerFn defines the handler used by slog.Handler as return value.

func NewOtelHandler

func NewOtelHandler(opts ...OtelHandlerOpt) HandlerFn

NewOtelHandler creates and returns a new HandlerFn, which wraps a handler with OtelHandler to use with log/slog.

type OtelHandler

type OtelHandler struct {
	// Next represents the next handler in the chain.
	Next slog.Handler
	// NoBaggage determines whether to add context baggage members to the log record.
	NoBaggage bool
	// NoTraceEvents determines whether to record an event for every log on the active trace.
	NoTraceEvents bool
}

func New

func New(next slog.Handler, opts ...OtelHandlerOpt) *OtelHandler

New creates a new OtelHandler to use with log/slog

func (OtelHandler) Enabled

func (h OtelHandler) Enabled(ctx context.Context, level slog.Level) bool

Enabled reports whether the logger emits log records at the given context and level. Note: We handover the decision down to the next handler.

func (OtelHandler) Handle

func (h OtelHandler) Handle(ctx context.Context, record slog.Record) error

Handle handles the provided log record and adds correlation between a slog record and an Open-Telemetry span.

func (OtelHandler) WithAttrs

func (h OtelHandler) WithAttrs(attrs []slog.Attr) slog.Handler

WithAttrs returns a new Otel whose attributes consists of handler's attributes followed by attrs.

func (OtelHandler) WithGroup

func (h OtelHandler) WithGroup(name string) slog.Handler

WithGroup returns a new Otel with a group, provided the group's name.

type OtelHandlerOpt

type OtelHandlerOpt func(handler *OtelHandler)

func WithNoBaggage

func WithNoBaggage(noBaggage bool) OtelHandlerOpt

WithNoBaggage returns an OtelHandlerOpt, which sets the NoBaggage flag

func WithNoTraceEvents

func WithNoTraceEvents(noTraceEvents bool) OtelHandlerOpt

WithNoTraceEvents returns an OtelHandlerOpt, which sets the NoTraceEvents flag
