Struct tracing_subscriber::filter::combinator::Not

source ·
pub struct Not<A, S> { /* private fields */ }
Expand description

Inverts the result of a Filter.

If the wrapped filter would enable a span or event, it will be disabled. If it would disable a span or event, that span or event will be enabled.

This type is typically returned by the FilterExt::not method. See that method’s documentation for details.
