High-level Michelson Data Types

Parsing and Typechecking Michelson

module Internal_for_benchmarking : sig ... end

For benchmarking purpose, we also export versions of the unparsing functions which don't call location stripping. These functions are not carbonated and should not be called directly from the protocol.

parse_ty specialized for the right-hand side part of a big map type, i.e. the `value` in `big_map key value`.

parse_ty allowing big_map values, operations, contract and tickets.

val parse_ty : Alpha_context.context -> legacy:bool -> allow_lazy_storage:bool -> allow_operation:bool -> allow_contract:bool -> allow_ticket:bool -> Alpha_context.Script.node -> (Script_typed_ir.ex_ty * Alpha_context.context) Tezos_protocol_environment_alpha.Error_monad.tzresult

We expose parse_ty for convenience to external tools. Please use specialized versions such as parse_packable_ty, parse_passable_ty, parse_comparable_ty, or parse_big_map_value_ty if possible.

High-level function to typecheck a Michelson script. This function is not used for validating operations but only for the typecheck_code RPC.

If show_types is set to true, details of the typechecking are returned in the type_map, otherwise the returned type_map is empty.

Combines parse_code and parse_storage

type 'a ex_ty_cstr =
  1. | Ex_ty_cstr : {
    1. ty : ('b, _) Script_typed_ir.ty;
    2. construct : 'b -> 'a;
    3. original_type_expr : Alpha_context.Script.node;
    } -> 'a ex_ty_cstr

'a ex_ty_cstr is like ex_ty, but also adds to the existential a function used to reconstruct a value of type 'a from the internal type of the existential. Typically, it will be used to go from the type of an entry-point to the full type of a contract.

val find_entrypoint : error_details:(_, 'error_trace) Script_tc_errors.error_details -> ('t, _) Script_typed_ir.ty -> 't Script_typed_ir.entrypoints -> Alpha_context.Entrypoint.t -> ('t ex_ty_cstr, 'error_trace) Gas_monad.t
type lazy_storage_ids
val no_lazy_storage_id : lazy_storage_ids

Traverse the given type, producing a lazy_storage_ids for use with extract_lazy_storage_diff.

val list_of_big_map_ids : lazy_storage_ids -> Alpha_context.Big_map.Id.t list

Produce a lazy storage diff, containing in-memory writes to lazy data structures such as big_maps yet to be committed.

The resulting diff can be committed to the underlying storage (context) using Lazy_storage_diff.apply.

  • parameter to_duplicate

    Lazy data structure reference produced via collect_lazy_storage that can not be reused. Typically collected via traversing the parameters to a smart contract.

  • parameter to_update

    Lazy data structure reference produced via collect_lazy_storage that can be reused. Typically collected via traversing the previous storage of a smart contract.

code_size ctxt code views returns an overapproximation of the size of the in-memory representation of code and views in bytes in the context ctxt.

val script_size : ex_script -> int * Gas_limit_repr.cost

script_size script returns an overapproximation of the size of the in-memory representation of script in bytes as well as the cost associated to computing that overapproximation.
