View Source Oban.Plugin behaviour (Oban v2.15.4)
Defines a shared behaviour for Oban plugins.
In addition to implementing the Plugin behaviour, all plugins must be a GenServer, Agent, or
another OTP compliant module.
Example
Defining a basic plugin that satisfies the minimum behaviour:
defmodule MyPlugin do
@behaviour Oban.Plugin
use GenServer
@impl Oban.Plugin
def start_link(opts) do
GenServer.start_link(__MODULE__, opts, name: opts[:name])
end
@impl Oban.Plugin
def validate(opts) do
if is_atom(opts[:mode])
:ok
else
{:error, "expected opts to have a :mode key"}
end
end
@impl GenServer
def init(opts) do
case validate(opts) do
:ok -> {:ok, opts}
{:error, reason} -> {:stop, reason}
end
end
endSummary
Callbacks
Starts a Plugin process linked to the current process.
Validate the structure, presence, or values of keyword options.
Types
@type option() :: {:conf, Oban.Config.t()} | {:name, GenServer.name()} | {atom(), term()}
Callbacks
@callback start_link([option()]) :: GenServer.on_start()
Starts a Plugin process linked to the current process.
Plugins are typically started as part of an Oban supervision tree and will receive the current
configuration as :conf, along with a :name and any other provided options.
