Wraps
self
and returns a MakeWriter
that will only write output
for events at or below the provided verbosity Level
. For instance,
Level::TRACE
is considered to be _more verbosethan

fn with_filter<F>(self, filter: F) -> WithFilter<Self, F>
Wraps
self
with a predicate that takes a span or event’s Metadata
and returns a bool
. The returned MakeWriter
’s
MakeWriter::make_writer_for
method will check the predicate to
determine if a writer should be produced for a given span or event. Read moreSource§fn and<B>(self, other: B) -> Tee<Self, B>where
