# Apache OpenDALâ„¢ Timeout Layer
`opendal-layer-timeout` applies deadlines to control operations and stateful I/O bodies.
## Use through `opendal`
Applications should normally enable this layer through the `opendal` facade with the
`layers-timeout` feature:
```shell
cargo add opendal --features layers-timeout
```
The layer is available as `opendal::layers::TimeoutLayer` 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-timeout
```
Pass a configured layer to `Operator::layer`:
```rust
use opendal_core::Operator;
use opendal_layer_timeout::TimeoutLayer;
fn add_layer(operator: Operator, layer: TimeoutLayer) -> Operator {
operator.layer(layer)
}
```
Construct and configure `layer` as described in the API documentation before
composing it with an operator.
Layer order matters when timeout is combined with retry. Review the API documentation
before composing both layers.
