Implementations

impl ResourceControlPolicy

pub fn no_fees() -> Self

Creates a policy with no cost for anything.

This can be used in tests or benchmarks.

pub fn maximum_fuel_per_block(&self, vm_runtime: VmRuntime) -> u64

The maximum fuel per block according to the VmRuntime.

pub fn only_fuel() -> Self

Creates a policy with no cost for anything except fuel.

This can be used in tests that need whole numbers in their chain balance.

pub fn all_categories() -> Self

Creates a policy where all categories have a small non-zero cost.

pub fn testnet() -> Self

Creates a policy that matches the Testnet.

pub fn total_price( &self, resources: &Resources, ) -> Result<Amount, ArithmeticError>

pub fn check_blob_size( &self, content: &BlobContent, ) -> Result<(), ExecutionError>
