pub struct LoggingLayer;
Expand description

LoggingLayer will add logging for OpenDAL.

Logging

  • OpenDAL will log in structural way.
  • Every operation will start with a started log entry.
  • Every operation will finish with the following status:
    • finished: the operation is successful.
    • errored: the operation returns an expected error like NotFound.
    • failed: the operation returns an unexpected error.

Todo

We should migrate to log’s kv api after it’s ready.

Tracking issue: https://github.com/rust-lang/log/issues/328

Examples

use anyhow::Result;
use opendal::layers::LoggingLayer;
use opendal::Operator;
use opendal::Scheme;

let _ = Operator::from_env(Scheme::Fs)
    .expect("must init")
    .layer(LoggingLayer);
