What's the difference between the gossipsub api in go and rust?

[harsh4786]

Specifically, does rust gossipsub support Join() like as seen in go libp2p? Or ,
subscribe() does exactly that behind the scenes?

[thomaseizinger]

As far as I understand, JOIN is an implementation detail of gossipsub and refers to a network message but it is not exposed explicitely.

See https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.0.md#topic-membership.

so does subscribe() internally call Join()?

hello @harsh4786 !

The subscribe() in rust implementation does the same work as Join() in go.
Both are used to indicate an interest in a particular topic and receive messages related to it. Therefore, it is safe to say that subscribe() in Rust performs the same action as Join() in Go.
