pub struct Failover<D1: Drain, D2: Drain> {
    // some fields omitted
}

Methods

impl<D1: Drain, D2: Drain> Failover<D1, D2>

fn new(drain1: D1, drain2: D2) -> Self

Create Failover

Trait Implementations

impl<D1: Drain, D2: Drain> Drain for Failover<D1, D2>

fn log(&self, buf: &mut Vec<u8>, info: &Record, logger_values: &OwnedKeyValueList) -> Result<()>

Write one logging record As an optimization (avoiding allocations), loggers are responsible for providing a byte buffer, that Drain can use for their own needs.
