33/// `LoggingLayer` records every operation with
34/// [log](https://docs.rs/log/).
35///
36/// # Logging
37///
38/// - OpenDAL emits structured logs.
39/// - Every operation starts with a `started` log entry.
40/// - Every operation ends with one of the following statuses:
41///   - `succeeded`: The operation succeeded but might have more work to perform.
42///   - `finished`: The whole operation finished.
43///   - `failed`: The operation returned an error.
44/// - The default log level for expected errors is `Warn`.
45/// - The default log level for unexpected errors is `Error`.
46///
47/// # Examples
48///
49/// ```no_run
50/// # use opendal_core::services;
51/// # use opendal_core::Operator;
52/// # use opendal_core::Result;
53/// # use opendal_layer_logging::LoggingLayer;
54/// #
55/// # fn main() -> Result<()> {
56/// let _ = Operator::new(services::Memory::default())?
57///     .layer(LoggingLayer::default());
58/// # Ok(())
59/// # }
60/// ```
61///
62/// # Output
63///
64/// OpenDAL uses [`log`](https://docs.rs/log/latest/log/) internally.
65///
66/// To enable logging output, please set `RUST_LOG`:
67///
68/// ```shell
69/// RUST_LOG=debug ./app
70/// ```
71///
72/// To config logging output, please refer to [Configure Logging](https://rust-lang-nursery.github.io/rust-cookbook/development_tools/debugging/config_log.html):
73///
74/// ```shell
75/// RUST_LOG="info,opendal::services=debug" ./app
76/// ```
77///
78/// # Logging Interceptor
79///
80/// You can implement your own logging interceptor to customize the logging behavior.
81///
82/// ```no_run
83/// # use opendal_core::raw;
84/// # use opendal_core::services;
85/// # use opendal_core::Error;
