An abstract type for keys
The type of values
Tells if a given key is already bound to a storage bucket
val get :
context ->
key ->
value Tezos_protocol_environment_alpha.Error_monad.tzresult
Tezos_protocol_environment_alpha.Lwt.tRetrieve a value from the storage bucket at a given key ; returns Storage_errorMissing_key if the key is not set ; returns Storage_errorCorrupted_data if the deserialisation fails.
val find :
context ->
key ->
value option Tezos_protocol_environment_alpha.Error_monad.tzresult
Tezos_protocol_environment_alpha.Lwt.tRetrieve a value from the storage bucket at a given key ; returns None if the value is not set ; returns Storage_error
Corrupted_data if the deserialisation fails.
val update :
context ->
key ->
value ->
Raw_context.t Tezos_protocol_environment_alpha.Error_monad.tzresult
Tezos_protocol_environment_alpha.Lwt.tUpdates the content of a bucket ; returns A Storage_Error
Missing_key if the value does not exists.
val init :
context ->
key ->
value ->
Raw_context.t Tezos_protocol_environment_alpha.Error_monad.tzresult
Tezos_protocol_environment_alpha.Lwt.tAllocates a storage bucket at the given key and initializes it ; returns a Storage_errorExisting_key if the bucket exists.
Allocates a storage bucket at the given key and initializes it with a value ; just updates it if the bucket exists.
val add_or_remove :
context ->
key ->
value option ->
Raw_context.t Tezos_protocol_environment_alpha.Lwt.tWhen the value is Some v, allocates the data and initializes it with v ; just updates it if the bucket exists. When the value is None, delete the storage bucket when the value ; does nothing if the bucket does not exists.
val remove_existing :
context ->
key ->
Raw_context.t Tezos_protocol_environment_alpha.Error_monad.tzresult
Tezos_protocol_environment_alpha.Lwt.tDelete a storage bucket and its contents ; returns a Storage_errorMissing_key if the bucket does not exists.
Removes a storage bucket and its contents ; does nothing if the bucket does not exists.
Empties all the keys and associated data.
Lists all the keys.
Lists all the keys and associated data.
