pub type Formatter<N = DefaultFields, E = Format, W = fn() -> Stdout> = Layered<Subscriber<Registry, N, E, W>, Registry>;
Available on crate features
fmt
and std
only.Expand description
A collector that logs formatted representations of tracing
events.
This type only logs formatted events; it does not perform any filtering.
