struct Channel

Declaration

struct Channel { /* full declaration omitted */ };

Description

Describes a Channel that messages are written to. A Channel represents a single connection from a publisher to a topic, so each topic will have one Channel per publisher. Channels optionally reference a Schema, for message encodings that are not self-describing (e.g. JSON) or when schema information is available (e.g. JSONSchema).
