```
InMemoryResource(AbsoluteUrl sourceUrl, Resource.Properties properties, SuspendFunction0<Try<ByteArray, ReadError>> bytes)
```
- Method Detail
  - getSourceUrl
```
 AbsoluteUrl getSourceUrl()
```
    URL locating this resource, if any.
  - properties
```
 Try<Resource.Properties, ReadError> properties()
```
    Properties associated to the resource.
    This is opened for extensions.
  - length
```
 Try<Long, ReadError> length()
```
    Returns data length from metadata if available, or calculated from reading the bytes otherwise.
    This value must be treated as a hint, as it might not reflect the actual bytes length. To get the real length, you need to read the whole resource.
  - read
```
 Try<ByteArray, ReadError> read(LongRange range)
```
    Reads the bytes at the given range.
    When range is null, the whole content is returned. Out-of-range indexes are clamped to the available length automatically.
  - close
```
 Unit close()
```
    Closes this object and releases any resources associated with it. If the object is already closed then invoking this method has no effect.
  - toString
```
 String toString()
```
