```kotlin
interface ChangeList
```
The ordered list of non-overlapping and discontinuous changes performed on a
[TextFieldBuffer](/jetpack-compose/androidx.compose.foundation/foundation/classes/TextFieldBuffer) during the current [edit](/jetpack-compose/androidx.compose.foundation/foundation/classes/TextFieldState) or
