Abstract Context

type t

Abstract view of the context. Includes a handle to the functional key-value database (Context.t) along with some in-memory values (gas, etc.).

Generic accessors

type key = string list
module type T = sig ... end

All context manipulation functions. This signature is included as-is for direct context accesses, and used in Storage_functors to provide restricted views to the context.

include T with type t := t and type context := context
val mem : context -> key -> bool Lwt.t

Tells if the key is already defined as a value.

val dir_mem : context -> key -> bool Lwt.t

Tells if the key is already defined as a directory.

val get : context -> key -> (value, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result Lwt.t

Retrieve the value from the storage bucket ; returns a Storage_errorMissing_key if the key is not set.

val get_option : context -> key -> value option Lwt.t

Retrieves the value from the storage bucket ; returns None if the data is not initialized.

val init : context -> key -> value -> (context, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result Lwt.t

Allocates the storage bucket and initializes it ; returns a Storage_errorExisting_key if the bucket exists.

val set : context -> key -> value -> (context, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result Lwt.t

Updates the content of the bucket ; returns a Storage_error Missing_key if the value does not exists.

val init_set : context -> key -> value -> context Lwt.t

Allocates the data and initializes it with a value ; just updates it if the bucket exists.

val set_option : context -> key -> value option -> context Lwt.t

When the value is Some v, allocates the data and initializes it with v ; just updates it if the bucket exists. When the valus is None, delete the storage bucket when the value ; does nothing if the bucket does not exists.

val delete : context -> key -> (context, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result Lwt.t

Delete the storage bucket ; returns a Storage_error Missing_key if the bucket does not exists.

val remove : context -> key -> context Lwt.t

Removes the storage bucket and its contents ; does nothing if the bucket does not exists.

val remove_rec : context -> key -> context Lwt.t

Recursively removes all the storage buckets and contents ; does nothing if no bucket exists.

val copy : context -> from:key -> to_:key -> (context, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result Lwt.t

val project : context -> root_context

Internally used in Storage_functors to escape from a view.

val absolute_key : context -> key -> key

val consume_gas : context -> Gas_limit_repr.cost -> (context, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result

Internally used in Storage_functors to consume gas from within a view.

val check_enough_gas : context -> Gas_limit_repr.cost -> (unit, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result

Check if consume_gas will fail

val description : context Storage_description.t
val reset_internal_nonce : context -> context

Initialize the local nonce used for preventing a script to duplicate an internal operation to replay it.

val fresh_internal_nonce : context -> (context * int, Tezos_protocol_environment_005_PsBABY5H__Environment.Error_monad.error list) Stdlib.result

Increments the internal operation nonce.

val record_internal_nonce : context -> int -> context

Mark an internal operation nonce as taken.

val internal_nonce_already_recorded : context -> int -> bool

Check is the internal operation nonce has been taken.

val allowed_endorsements : context -> (Tezos_crypto.Signature.public_key * int list * bool) Tezos_protocol_environment_005_PsBABY5H__Environment.Signature.Public_key_hash.Map.t

Returns a map where to each endorser's pkh is associated the list of its endorsing slots (in decreasing order) for a given level.

val included_endorsements : context -> int

Keep track of the number of endorsements that are included in a block

val init_endorsements : context -> (Tezos_crypto.Signature.public_key * int list * bool) Tezos_protocol_environment_005_PsBABY5H__Environment.Signature.Public_key_hash.Map.t -> context

Initializes the map of allowed endorsements, this function must only be called once.

Marks an endorsment in the map as used.

val fresh_temporary_big_map : context -> context * Z.t

Provide a fresh identifier for a temporary big map (negative index).

val reset_temporary_big_map : context -> context

Reset the temporary big_map identifier generator to -1.

val temporary_big_maps : context -> ('a -> Z.t -> 'a Lwt.t) -> 'a -> 'a Lwt.t
