Struct Logger

pub struct Logger { /* private fields */ }

A logger that sends JSON formatted logs to a list in a Redis instance. It uses this format

  {
    "@timestamp": ${timeRFC3339},
    "@source_host": ${hostname},
    "@message": ${message},
    "@fields": {
       "level": ${levelLowercase},
       "application": ${appName}
       ... // logged field 1
       ... // logged field 2
       ...
   }

It supports structured logging via slog. You can use the Builder to construct it and then use it as an slog drain.

Trait Implementations

impl Debug for Logger

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drain for Logger

type Ok = ()

Type returned by this drain

type Err = Error

Type of potential errors that can be returned by this Drain

fn log( &self, record: &Record<'_>, values: &OwnedKVList, ) -> Result<Self::Ok, Self::Err>

Handle one logging statement (Record)
