Functions

func Level

func Level(s string) slog.Level

Level maps a string to slog.Level. Unknown values default to Info. Accepts (case-insensitive): "debug", "info", "warn", "warning", "error".

func SafeField

func SafeField(s string) string

SafeField strips C0 control characters and DEL from s, returning a string safe to include as a structured log field value. Use it to wrap any field derived from HTTP input (paths, headers, query strings, error messages carrying user data) before passing to slog, to prevent log forging via embedded newlines or terminal escape sequences.
