Struct sc_tracing::logging::PrefixLayer
source · pub struct PrefixLayer;
Expand description
A Layer
that captures the prefix span (PREFIX_LOG_SPAN
) which is then used by
crate::logging::EventFormat
to prefix the log lines by customizable string.
See the macro sc_cli::prefix_logs_with!
for more details.
