Retrieves the history from a given cache.

val dal_mk_polynomial_from_slot : 
  bytes ->
  Tezos_crypto_dal.Cryptobox.polynomial Tezos_base.TzPervasives.tzresult

Returns the slot's polynomial from the given slot's data.

  Tezos_protocol_alpha.Protocol.Dal_slot_repr.Page.t ->
  Tezos_crypto_dal.Cryptobox.page_proof Tezos_base.TzPervasives.tzresult

Using the given slot's polynomial, this function computes the page proof of the page whose ID is provided.

  (bytes
   * Tezos_crypto_dal.Cryptobox.polynomial
   * Tezos_protocol_alpha.Protocol.Dal_slot_repr.Header.t)
    Tezos_base.TzPervasives.tzresult

Constructs a slot whose ID is defined from the given level and given index, and whose data are built using the given fill function. The function returns the slot's data, polynomial, and header (in the sense: ID + kate commitment).

val mk_page_id : 
  Tezos_protocol_alpha.Protocol.Raw_level_repr.t ->
  Tezos_protocol_alpha.Protocol.Dal_slot_index_repr.t ->
  int ->
  Tezos_protocol_alpha.Protocol.Dal_slot_repr.Page.t

Constructs a record value of type Page.id.

   * Tezos_protocol_alpha.Protocol.Dal_slot_repr.Page.t,
    Tezos_base.TzPervasives.error Tezos_base.TzPervasives.trace)
    Stdlib.result

Constructs a page whose level and slot indexes are those of the given slot (except if level is redefined via ?level), and whose page index and data are given by arguments page_index and mk_data. If mk_data is set to No, the function returns the pair (None, page_id). Otherwise, the page's data and proof is computed, and the function returns Some (data, proof), page_id.

val next_char : char -> char

Returns the char after c. Restarts from the char whose code is 0 if c's code is 255.

val succ_slot_index : 
  Tezos_protocol_alpha.Protocol.Dal_slot_index_repr.t ->
  Tezos_protocol_alpha.Protocol.Dal_slot_index_repr.t

Increment the given slot index. Returns zero in case of overflow.

  page_id:Tezos_protocol_alpha.Protocol.Dal_slot_repr.Page.t ->
  (unit, Tezos_base.TzPervasives.tztrace) Stdlib.result Lwt.t

Auxiliary test function used by both unit and PBT tests: This function produces a proof from the given information and verifies the produced result, if any. The result of each step is checked with check_produce_result and check_verify_result, respectively.

val eq_page_proof : 
  Tezos_crypto_dal.Cryptobox.page_proof ->
  Tezos_crypto_dal.Cryptobox.page_proof ->
  bool

Check if two page proofs are equal.

Helper for the case where produce_proof is expected to fail because the slot is confirmed but no page information are provided.

val slot_not_confirmed_but_page_data_provided : 
  __LOC__:string ->
  'a Tezos_base.TzPervasives.tzresult ->
  'b ->
  unit Tezos_base.TzPervasives.tzresult Lwt.t

Helper for the case where produce_proof is expected to fail because the slot is not confirmed but page_info are provided.
