Capsule corresponds to the values created with Py.Capsule. Closure corresponds to the values created with Py.Callable.

Sourceval get : Object.t -> t

get o returns the type of the Python value o.

Sourceval is_subtype : Object.t -> Object.t -> bool

Wrapper for PyType_IsSubtype

Sourceval is_none : Object.t -> bool

is_none o returns true if the Python object o is None.

Sourceval name : t -> string

name t returns a string that represents the type t.

Sourceval mismatch : string -> Object.t -> 'a

mismatch ty obj raises a type mismatch Failure _ that indicates that an object of type ty was expected, but obj was found.

Sourceval create : string -> Object.t list -> (string * Object.t) list -> Object.t

create classname parents dict calls Python type() function to create a new type classname deriving from parents with the dictionary dict.
