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

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.

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 verbosethanLevel::INFO`. Read more

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 more
