Struct pallet_contracts::Schedule

pub struct Schedule<T: Config> {
    pub limits: Limits,
    pub instruction_weights: InstructionWeights<T>,
    pub host_fn_weights: HostFnWeights<T>,
}

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 {
		        memory_pages: 16,
		        .. 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>

The weights for each imported function a contract is allowed to call.

Trait Implementations

impl<T: Clone + Config> Clone for Schedule<T>

fn clone(&self) -> Schedule<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Config> Decode for Schedule<T>

where InstructionWeights<T>: Decode, HostFnWeights<T>: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T: Config> Default for Schedule<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T: Config> Deserialize<'de> for Schedule<T>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Config> Encode for Schedule<T>

where InstructionWeights<T>: Encode, HostFnWeights<T>: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: PartialEq + Config> PartialEq for Schedule<T>

fn eq(&self, other: &Schedule<T>) -> 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.

impl<T: Config> Serialize for Schedule<T>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> TypeInfo for Schedule<T>

where InstructionWeights<T>: TypeInfo + 'static, HostFnWeights<T>: TypeInfo + 'static, T: Config + 'static,

type Identity = Schedule<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<T: Config> EncodeLike for Schedule<T>

where InstructionWeights<T>: Encode, HostFnWeights<T>: Encode,

impl<T: Eq + Config> Eq for Schedule<T>

impl<T: Config> StructuralPartialEq for Schedule<T>
