Struct near_vm_logic::VMConfig

pub struct VMConfig {
    pub ext_costs: ExtCostsConfig,
    pub grow_mem_cost: u32,
    pub regular_op_cost: u32,
    pub limit_config: VMLimitConfig,
}

Dynamic configuration parameters required for the WASM runtime to execute a smart contract.

This (VMConfig) and RuntimeFeesConfig combined are sufficient to define protocol specific behavior of the contract runtime. The former contains configuration for the WASM runtime specifically, while the latter contains configuration for the transaction runtime and WASM runtime.

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.

limit_config: VMLimitConfig

Describes limits for VM and Runtime.

Implementations

impl VMConfig

pub fn test() -> 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

Trait Implementations

impl Clone for VMConfig

fn clone(&self) -> VMConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VMConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<VMConfigView> for VMConfig

fn from(view: VMConfigView) -> VMConfig

Converts to this type from the input type.

impl Hash for VMConfig

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<VMConfig> for VMConfig

fn eq(&self, other: &VMConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
