Functions

func FromContextOrDiscard

func FromContextOrDiscard(ctx context.Context) logr.Logger

FromContextOrDiscard returns a logger with trace and span IDs populated from the context if they exist. In order to get logger without span, use logr.FromContextOrDiscard(ctx context.Context).

func NewLogger

func NewLogger(name string, options *LoggingOptions) (logr.Logger, func(), error)

NewLogger creates a new logger with zap logger implementation, with the given name and logging options, and returns a function to flush the logs before the server exits.

func NewResourceObject

func NewResourceObject(serviceName string) []any

This function creates a new resource object with the given service name, hostname and version.

func Unwrap

func Unwrap(logger logr.Logger) *zap.Logger

Unwrap attempts to extract the underlying zap.Logger from a logr.Logger, returning nil if it fails.

func WrapLogContext

func WrapLogContext(ctx context.Context, keyValues ...any) context.Context

WrapLogContext adds key-value pairs to the context's logger for logging purposes.
