class MessageHandleBase

Defined at line 47 of file ../../third_party/perfetto/include/perfetto/protozero/message_handle.h

MessageHandle allows to decouple the lifetime of a proto message

from the underlying storage. It gives the following guarantees:

- The underlying message is finalized (if still alive) if the handle goes

out of scope.

- In Debug / DCHECK_ALWAYS_ON builds, the handle becomes null once the

message is finalized. This is to enforce the append-only API. For instance

when adding two repeated messages, the addition of the 2nd one forces

the finalization of the first.

Think about this as a WeakPtr

<Message

> which calls

Message::Finalize() when going out of scope.

ScatteredStreamWriter * TakeStreamWriter ()

Returns a (non-owned, it should not be deleted) pointer to the

ScatteredStreamWriter used to write the message data. The Message becomes

unusable after this point.

The caller can now write directly, without using protozero::Message.
