Struct tracing_subscriber::fmt::writer::WithMaxLevel
source · [−]pub struct WithMaxLevel<M> { /* private fields */ }Expand description
A MakeWriter combinator that only returns an enabled writer for spans
and events with metadata at or below a specified verbosity Level.
This is returned by the MakeWriterExt::with_max_level method. See the
method documentation for details.
Implementations
sourceimpl<M> WithMaxLevel<M>
impl<M> WithMaxLevel<M>
sourcepub fn new(make: M, level: Level) -> Self
pub fn new(make: M, level: Level) -> Self
Wraps the provided MakeWriter with a maximum Level, so that it
returns OptionalWriter::none for spans and events whose level is
more verbose than the maximum level.
See MakeWriterExt::with_max_level for details.

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 more
