Struct slog::LevelFilter
source · pub struct LevelFilter<D: Drain>(pub D, pub Level);Expand description
Drain filtering records by Record logging level
Wraps a drain and passes records to it, only if their level is at least given level.
TODO: Remove this type. This drain is a special case of Filter, but
because Filter can not use static dispatch ATM due to Rust limitations
that will be lifted in the future, it is a standalone type.
