class LittleGhost::Runtime::Hook

Hooks let applications prepare runs, transform interruptions, and map errors to caller-safe messages.

Hooks are instantiated once per Runtime in configuration order. Override only the methods needed and return the supplied value when leaving it unchanged.

class TenantHook < LittleGhost::Runtime::Hook
  def prepare_run(run)
    run.register(TenantConnection.new(run.invocation.actor_id))
    run
  end
end

Source

# File lib/little_ghost/runtime/hook.rb, line 24
def prepare_interruption(_run, payload) = payload

Transforms an interruption payload before it reaches the agent.

Source

# File lib/little_ghost/runtime/hook.rb, line 21
