template <typename FieldMetadata>struct TypedProtoWriter
Defined at line 330 of file ../../third_party/perfetto/include/perfetto/tracing/traced_proto.h
TypedProtoWriter takes the protozero message (TracedProto
<MessageType
>),
field description (FieldMetadata) and value and writes the given value
into the given field of the given protozero message.
This is primarily used for inline writing of typed messages:
TRACE_EVENT(..., pbzero::Message:kField, value);
Ideally we would use a function here and not a struct, but passing template
arguments directly to the function (e.g. foo
<void
>()) isn't supported until
C++20, so we have to use a helper struct here.
