Mavryk_raw_protocol_alpha.Sc_rollup_costsThis module contains constants and utility functions for gas metering functions used when handling SC rollups operations in context.
module Constants : sig ... endval is_valid_parameters_ty_cost :
ty_size:'a Saturation_repr.t ->
Saturation_repr.may_saturate Saturation_repr.tis_valid_parameters_ty_cost ty returns the cost of checking whether a type is a valid sc rollup parameter.
val cost_serialize_internal_inbox_message :
Sc_rollup_inbox_message_repr.internal_inbox_message ->
Gas_limit_repr.costcost_serialize_internal_inbox_message internal_inbox_message is the cost of the serialization of an internal inbox message. It's equal to the cost of serializing the script expression, with Script_repr.force_bytes_cost plus a fixed amount for the serialized addresses.
It traverses the payload expression to find the precise cost. It is safe to use Script_repr.force_bytes_cost because the payload of an internal inbox message is bounded.
val cost_deserialize_output_proof : bytes_len:int -> Gas_limit_repr.costcost_deserialize_output_proof ~bytes_len is the cost of the deserialization of an output proof.
val cost_serialize_external_inbox_message :
bytes_len:int ->
Gas_limit_repr.costcost_serialize_external_inbox_message ~bytes_len is the cost of the serialization of an external inbox message of length bytes_len. It is equal to the estimated cost of encoding a byte multiplied by bytes_len.
val cost_hash_bytes : bytes_len:int -> Gas_limit_repr.costcost_hash_bytes ~bytes_len is the cost of hashing bytes_len bytes.
val cost_check_dissection :
number_of_states:int ->
tick_size:int ->
hash_size:int ->
Gas_limit_repr.costcost_check_dissection ~number_of_states ~tick_size ~hash_size is the cost of checking that a dissection with a given number_of_states used in a refutation game is well-formed. This includes the comparison of a linear number of ticks as well as the verification of two hashes of given hash_size.
val cost_verify_output_proof : bytes_len:int -> Gas_limit_repr.costcost_verify_output_proof ~bytes_len is the cost of verifying an output proof of length bytes_len.
val cost_add_message :
current_index:Mavryk_protocol_environment_alpha.Z.t ->
msg_len:int ->
Gas_limit_repr.costcost_add_message ~new_cell_index ~msg_len returns the cost of adding a message of length msg_len to a sc-rollup inbox. This function is used internally in the Sc_rollup_storage module and covers the function Sc_rollup_inbox_merkelized_payload_hashes_repr.add_payload
val cost_install_boot_sector_in_wasm_pvm :
boot_sector_size_in_bytes:int ->
Gas_limit_repr.costcost_install_boot_sector_in_wasm_pvm ~boot_sector_size_in_bytes returns the cost of installing a boot sector in an empty WASM PVM state. This function is used in the implementation of the origination.
