}
Expand description

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

Its Default implementation is the designated way to initialize this type. It uses the benchmarked information supplied by Config::WeightInfo. All of its fields are public and can therefore be modified. For example in order to change some of the limits and set a custom instruction weight version the following code could be used:

use pallet_contracts::{Schedule, Limits, InstructionWeights, Config};

fn create_schedule<T: Config>() -> Schedule<T> {
    Schedule {
        limits: Limits {
		        globals: 3,
		        parameters: 3,
		        memory_pages: 16,
		        table_size: 3,
		        br_table_size: 3,
		        .. Default::default()
	        },
        instruction_weights: InstructionWeights {
            .. Default::default()
        },
	        .. Default::default()
    }
}

Fields§

§limits: Limits

Describes the upper limits on various metrics.

§instruction_weights: InstructionWeights<T>

The weights for individual wasm instructions.

§host_fn_weights: HostFnWeights<T>
