Struct slog::MapError

pub struct MapError<D: Drain, E> {
    // some fields omitted
}

Map error of a Drain

Methods

impl<D: Drain, E> MapError<D, E>

fn new<F: 'static + Sync + Send + Fn(D::Error) -> E>(drain: D, map_fn: F) -> Self

Create Filter wrapping given subdrain and passing to it records only the cond is true

Trait Implementations

impl<D: Drain, E> Drain for MapError<D, E>

type Error = E

Type of potential error returned during logging

fn log(&self, info: &Record, logger_values: &OwnedKeyValueList) -> Result<(), Self::Error>

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.
