hound v1.0.2 Hound.Metadata
Metadata allows to pass and extract custom data through. This can be useful if you need to identify sessions.
The keys and values must be serializable using :erlang.term_to_binary/1
.
Examples
You can start a session using metadata by doing the following:
Hound.start_session(metadata: %{pid: self()})
If you need to retrieve the metadata, you simply need to use
Hound.Metadata.extract/1
on the user agent string, so supposing you are using plug,
user_agent = conn |> get_req_header("user-agent") |> List.first
metadata = Hound.Metadata.extract(user_agent)
assert %{pid: pid} = metadata
# you can use your pid here
