[Question] How to handle cl-defstructs from other, require'd packages?

[nbfalcon]

In my project I require flycheck and make use of one of its types: flycheck-error. It is defined with cl-defstruct. When I specify a type signature making use of it (as per the readme, just specifying the struct name) as '(flycheck-projectile-buffer-errors :: Buffer -> [flycheck-error])', I get an error: Unknown type flycheck-error.

Can Elsa follow requires, or is there some way to define types for elsa explicitly?

There is currently no support for defstruct or classes.

There is now support for defstruct and defclass, both create a type (struct NAME). The support for defclass is currently better as cl-defstruct does not include inheritance yet.
