[src]
pub struct Filter<D: Drain, F>(pub D, pub F) where F: Fn(&Record) -> bool + 'static + Send + Sync;
Drain filtering records
Wraps another Drain and passes Records to it, only if they satisfy a
given condition.
Methods
impl<D: Drain, F> Filter<D, F> where F: FilterFn[src]
fn new(drain: D, cond: F) -> Self
