func Level() slog.Level

Level reports the level currently in effect.

func LevelName(l slog.Level) string

LevelName renders a level the way ParseLevel accepts it.

func ParseLevel(s string) slog.Level

ParseLevel maps a level name (case-insensitive) to a slog.Level, defaulting to info.

func SetLevel(l slog.Level)

SetLevel changes the level for the remaining lifetime of the process and cancels any pending auto-revert.

func SetLevelFor(l slog.Level, ttl time.Duration)

SetLevelFor changes the level for ttl, then restores the previous level. ttl <= 0 is treated as a permanent SetLevel.

func Setup(service string)

Setup installs a JSON handler on stdout tagged with the service name. Initial level comes from LOG_LEVEL; unrecognised or empty values select info.

func String() string

String renders the active level name.

func Var() *slog.LevelVar

Var exposes the LevelVar for a handler built outside Setup (tests, tooling).
