Interface
Common
> **Deprecated** Customization of PrefetchScheduler is no longer supported. LazyLayout will attach an appropriate scheduler internally. If you needed to customize it please file a Feature Request.
```kotlin
@ExperimentalFoundationApi
interface PrefetchScheduler
```
Implementations of this interface accept prefetch requests via `schedulePrefetch` and decide when
to execute them in a way that will have minimal impact on user experience, e.g. during frame idle
time.
Requests should be executed by invoking `PrefetchRequest.execute`. The implementation of
`PrefetchRequest.execute` will return `false` when all work for that request is done, or `true`
when it still has more to do but doesn't think it can complete it within
`PrefetchRequestScope.availableTimeNanos`.
## Functions
schedulePrefetch
```kotlin
fun schedulePrefetch(prefetchRequest: PrefetchRequest)
```
Accepts a prefetch request. Implementations should find a time to execute them which will
have minimal impact on user experience.
