Fields

ext_costs: ExtCostsConfig

Costs for runtime externals

grow_mem_cost: u32

Gas cost of a growing memory by single page.

regular_op_cost: u32

Gas cost of a regular operation.

max_gas_burnt: u64

Max amount of gas that can be used, excluding gas attached to promises.

max_stack_height: u32

How tall the stack is allowed to grow?

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

initial_memory_pages: u32

The initial number of memory pages.

max_memory_pages: u32

What is the maximal memory pages amount is allowed to have for a contract.

registers_memory_limit: u64

Limit of memory used by registers.

max_register_size: u64

Maximum number of bytes that can be stored in a single register.

max_number_registers: u64

Maximum number of registers that can be used simultaneously.

max_number_logs: u64

Maximum number of log entries.

max_log_len: u64

Maximum length of a single log, in bytes.

Methods

impl VMConfig

pub fn non_crypto_hash(&self) -> u64

Computes non-cryptographically-proof hash. The computation is fast but not cryptographically secure.

pub fn free() -> VMConfig
