Fields

regular: u32

Default opcode cost

div: u32

Div operations multiplier.

mul: u32

Mul operations multiplier.

mem: u32

Memory (load/store) operations multiplier.

initial_mem: u32

Memory stipend. Amount of free memory (in 64kb pages) each contract can use for stack.

grow_mem: u32

Grow memory cost, per page (64kb)

memcpy: u32

Memory copy cost, per byte

max_stack_height: u32

Max stack height (native WebAssembly stack limiter)

opcodes_mul: u32

Cost of wasm opcode is calculated as TABLE_ENTRY_COST * opcodes_mul / opcodes_div

opcodes_div: u32

Cost of wasm opcode is calculated as TABLE_ENTRY_COST * opcodes_mul / opcodes_div

Trait Implementations

impl Clone for WasmCosts

fn clone(&self) -> WasmCosts

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for WasmCosts

impl Debug for WasmCosts

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for WasmCosts

fn default() -> WasmCosts

Returns the "default value" for a type.

impl Eq for WasmCosts

impl FromBytes for WasmCosts

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq<WasmCosts> for WasmCosts

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

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

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

This method tests for !=.

impl StructuralEq for WasmCosts

impl StructuralPartialEq for WasmCosts

impl ToBytes for WasmCosts

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

Consumes self and serializes to a Vec<u8>.
