Middleware

Decorator used to register middleware with priority ordering. The lower the priority number, the earlier it runs.

Interaction middleware cannot specify event filters.

Throws:

A SeedcordTypeError If priority is not a finite number
A SeedcordError If interaction middleware specifies event filters
