Struct tracing_subscriber::fmt::writer::WithFilter

source · [−]

pub struct WithFilter<M, F> { /* private fields */ }

Expand description

A MakeWriter combinator that wraps a MakeWriter with a predicate for span and event Metadata, so that the MakeWriter::make_writer_for method returns OptionalWriter::some when the predicate returns true, and OptionalWriter::none when the predicate returns false.

This is returned by the MakeWriterExt::with_filter method. See the method documentation for details.

Implementations

source

impl<M, F> WithFilter<M, F>

source

pub fn new(make: M, filter: F) -> Self where
F: Fn(&Metadata<'_>) -> bool,

Wraps make with the provided filter, returning a MakeWriter that will call make.make_writer_for() when filter returns true for a span or event’s Metadata, and returns a sink otherwise.

See MakeWriterExt::with_filter for details.
