Struct slog_vmodule::ModLevelFilter

pub struct ModLevelFilter<D: Drain> { /* fields omitted */ }

Drain filtering records by Record logging level. If the record's emitter logger has module name set, only records with at least given module level will pass. If the module name is not set or there's no correspondent module level config, the default logging level will be used.

For more usage examples check README and test code.
