# Apache OpenDALâ„¢ Logging Layer
`opendal-layer-logging` records OpenDAL operation lifecycles with the `log` facade.
## Use through `opendal`
Applications should normally enable this layer through the `opendal` facade with the
`layers-logging` feature:
```shell
cargo add opendal --features layers-logging
```
The layer is available as `opendal::layers::LoggingLayer` and can be
composed with an operator through `opendal::Operator::layer`.
## Use with `opendal-core`
Add the split crates directly:
```shell
cargo add opendal-core opendal-layer-logging
```
Pass a configured layer to `Operator::layer`:
```rust
use opendal_core::Operator;
use opendal_layer_logging::LoggingLayer;
fn add_layer(operator: Operator, layer: LoggingLayer) -> Operator {
operator.layer(layer)
}
```
Construct and configure `layer` as described in the API documentation before
composing it with an operator.
