Struct tracing_subscriber::filter::Filtered
source · [−]pub struct Filtered<L, F, S> { /* private fields */ }
registry
only.Expand description
A Layer
that wraps an inner Layer
and adds a Filter
which
controls what spans and events are enabled for that layer.
This is returned by the Layer::with_filter
method. See the
documentation on per-layer filtering for details.
Implementations
sourceimpl<L, F, S> Filtered<L, F, S>
impl<L, F, S> Filtered<L, F, S>
sourcepub fn new(layer: L, filter: F) -> Self
This is supported on crate feature std
only.
pub fn new(layer: L, filter: F) -> Self
std
only.Wraps the provided Layer
so that it is filtered by the given
Filter
.
This is equivalent to calling the Layer::with_filter
method.
See the documentation on per-layer filtering for details.
