Some(content length) if a length is defined for this entity, None otherwise. A length is only defined for Strict and Default entity types.
In many cases it's dangerous to rely on the (non-)existence of a content-length. HTTP intermediaries like (transparent) proxies are allowed to change the transfer-encoding which can result in the entity being delivered as another type as expected.

Note: It is crucial that entities are either discarded, or consumed by running the underlying akka.stream.scaladsl.Source as otherwise the lack of consuming of the data will trigger back-pressure to the underlying TCP connection (as designed), however possibly leading to an idle-timeout that will close the connection, instead of just having ignored the data.
Warning: It is not allowed to discard and/or consume the entity.dataBytes
more than once
as the stream is directly attached to the "live" incoming data source from the underlying TCP connection.
Allowing it to be consumable twice would require buffering the incoming data, thus defeating the purpose
of its streaming nature. If the dataBytes source is materialized a second time, it will fail with an
"stream can cannot be materialized more than once" exception.
In future versions, more automatic ways to warn or resolve these situations may be introduced, see issue #18716.

Returns a copy of the given entity with the ByteString chunks of this entity transformed by the given transformer.
For a Chunked
entity, the chunks will be transformed one by one keeping the chunk metadata (but may introduce an
extra chunk before the LastChunk
if transformer.onTermination
returns additional data).
This method may only throw an exception if the transformer
function throws an exception while creating the transformer.
Any other errors are reported through the new entity data stream.
