Can I specify different level for appenders?

For example, "Info" for console, "Trace" for file, etc.

Yep, you can attach a threshold filter to them!

I tried like below:

refresh_rate: 30 seconds
appenders:
  stdout:
    kind: console
    encoder:
      pattern: "{d(%Y-%m-%d %H:%M:%S)} [{h({l})}] {m}{n}"
  decode:
    kind: file
    path: "log/debug.log"
    append: false
    filters:
      -
        kind: threshold
        level: debug
    encoder:
      pattern: "{d(%Y-%m-%d %H:%M:%S)} [{l}] - {M} - {m}{n}"
root:
  level: info
  appenders:
    - stdout
    - decode

But got a error:

log4rs: error deserializing component: no filter deserializer for kind threshold registered

Solved:
Should add the "threshold_filter" to Cargo.toml:

log4rs = { version = "*", features = ["threshold_filter"] }

Yep, it's not part of the default feature set. Glad you got it working!
