pw::channel::PacketChannel< T, kProperties > Class Template Reference
pw_channel » Packets

Overview

template<typename T, Property... kProperties>
class pw::channel::PacketChannel< T, kProperties >

Interface that supports reading and writing writing packets. The supported operations are reflected in the type.

PacketChannel is typically referred to by one its aliases: pw::channel::PacketReader, pw::channel::PacketWriter, or pw::channel::PacketReaderWriter.

To implement a packet channel, derive from pw::channel::Implement<> with the desired PacketChannel type.
