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

Fields

version: u32

Version of the schedule.

regular_op_cost: Gas

Gas cost of a regular operation.

grow_mem_cost: Gas

Gas cost of a growing memory by single page.

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_table_size: u32

Maximum allowed size of a declared table.

max_memory_pages: u32

Maximum number of memory pages.

has_forbidden_floats: bool

Floats are forbidden

has_grow_cost: bool

Cost of memory growth

has_metering: bool

Is metering on

has_table_size_limit: bool

Is table size limit on

per_type_op_cost: HashMap<String, u32>

Op cost bit

Implementations

impl Schedule

pub fn with_version(version: u32) -> Self

Create schedule with version

Trait Implementations

impl Clone for Schedule

fn clone(&self) -> Schedule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Schedule

fn default() -> Schedule

Returns the “default value” for a type.

impl PartialEq for Schedule

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

Tests for self and other values to be equal, and is used by ==.

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

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