Module Tezos_raw_protocol_015_PtLimaPt.Sc_rollup_costsSource
This module contains constants and utility functions for gas metering functions used when handling SC rollups operations in context.
val 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_add_serialized_messages :
num_messages:int ->
total_messages_size:int ->
int32 ->
Gas_limit_repr.costcost_add_serialized_messages ~num_messages ~total_messages_length level returns the cost of adding num_messages with total messages size total_messages_size to a sc-rollup inbox at level level. This function is used internally in the Sc_rollup_storage module.
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.
cost_deserialize_output_proof ~bytes_len is the cost of the deserialization of an output proof. It's equal to the cost of deserializing a script expression of size bytes_len.
cost_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.
cost_hash_bytes ~bytes_len is the cost of hashing bytes_len bytes.
