Struct tracing_forest::printer::MakeStderr
source · pub struct MakeStderr;
Expand description
A MakeWriter
that writes to stderr.
This is functionally the same as using std::io::stderr
as a MakeWriter
,
except it has a named type and can therefore be used in type signatures.

fn with_max_level(self, level: Level) -> WithMaxLevel<Self>where Self: Sized,
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
Level::INFO`. Read moresource§fn with_min_level(self, level: Level) -> WithMinLevel<Self>where

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
