Kernel implementation of sections.

type 'a t

Type of sections with additional data 'a

val depth : 'a t -> int

Number of nested sections.

val map_custom : ('a -> 'a) -> 'a t -> 'a t

Modify the custom data

Manipulating sections
type section_entry =
  1. | SecDefinition of Names.Constant.t
  2. | SecInductive of Names.MutInd.t
val open_section : custom:'a -> 'a t option -> 'a t

Open a new section with the provided universe polymorphic status. Sections can be nested, with the proviso that polymorphic sections cannot appear inside a monomorphic one. A custom data can be attached to this section, that will be returned by close_section.

val close_section : 'a t -> 'a t option * section_entry list * Univ.ContextSet.t * 'a

Close the current section and returns the entries defined inside, the set of global monomorphic constraints added in this section, and the custom data provided at the opening of the section.

Extending sections
val push_local : 'a t -> 'a t

Extend the current section with a local definition (cf. push_named).

val push_context : Univ.UContext.t -> 'a t -> 'a t

Extend the current section with a local universe context. Assumes that the last opened section is polymorphic.

val push_constraints : Univ.ContextSet.t -> 'a t -> 'a t

Extend the current section with a global universe context. Assumes that the last opened section is monomorphic.

val push_constant : poly:bool -> Names.Constant.t -> 'a t -> 'a t

Make the constant as having been defined in this section.

val push_inductive : poly:bool -> Names.MutInd.t -> 'a t -> 'a t

Make the inductive block as having been defined in this section.

Retrieving section data
val all_poly_univs : 'a t -> Univ.Level.t array

Returns all polymorphic universes, including those from previous sections. Earlier sections are earlier in the array.

NB: even if the array is empty there may be polymorphic constraints about monomorphic universes, which prevent declaring monomorphic globals.

val empty_segment : Declarations.abstr_info

Nothing to abstract

val segment_of_constant : Environ.env -> Names.Constant.t -> 'a t -> Declarations.abstr_info

Section segment at the time of the constant declaration

val segment_of_inductive : Environ.env -> Names.MutInd.t -> 'a t -> Declarations.abstr_info

Section segment at the time of the inductive declaration

val replacement_context : Environ.env -> 'a t -> Declarations.work_list

Section segments of all declarations from this section.

val is_in_section : Environ.env -> Names.GlobRef.t -> 'a t -> bool
