Definition of the cost schedule and other parameterizations for wasm vm.

Fields

version: u32

Version of the schedule.

put_code_per_byte_cost: Gas

Cost of putting a byte of code into storage.

grow_mem_cost: Gas

Gas cost of a growing memory by single page.

regular_op_cost: Gas

Gas cost of a regular operation.

return_data_per_byte_cost: Gas

Gas cost per one byte returned.

event_data_per_byte_cost: Gas

Gas cost to deposit an event; the per-byte portion.

event_per_topic_cost: Gas

Gas cost to deposit an event; the cost per topic.

event_base_cost: Gas

Gas cost to deposit an event; the base.

call_base_cost: Gas

Base gas cost to call into a contract.

instantiate_base_cost: Gas

Base gas cost to instantiate a contract.

sandbox_data_read_cost: Gas

Gas cost per one byte read from the sandbox memory.

sandbox_data_write_cost: Gas

Gas cost per one byte written to the sandbox memory.

max_event_topics: u32

The maximum number of topics supported by an event.

max_stack_height: u32

Maximum allowed stack height.

See https://wiki.parity.io/WebAssembly-StackHeight to find out how the stack frame cost is calculated.

max_memory_pages: u32

Maximum number of memory pages allowed for a contract.

max_table_size: u32

Maximum allowed size of a declared table.

enable_println: bool

Whether the ext_println function is allowed to be used contracts. MUST only be enabled for dev chains, NOT for production chains

max_subject_len: u32

The maximum length of a subject used for PRNG generation.
