Struct slog::Fuse [−][src]
Drain
panicking on error
Logger
requires a root drain to handle all errors (Drain::Error == ()
),
Fuse
will wrap a Drain
and panic if it returns any errors.
Note: Drain::Err
must implement Display
(for displaying on panic). It’s
easy to create your own Fuse
drain if this requirement can’t be fulfilled.
