Struct pallet_contracts::InstructionWeights

pub struct InstructionWeights<T: Config> {
    pub base: u32,
    pub _phantom: PhantomData<T>,
}

Gas metering of Wasm executed instructions is being done on the engine side. This struct holds a reference value used to gas units scaling between host and engine.

Fields

base: u32

Base instruction ref_time Weight. Should match to wasmi’s 1 fuel (see https://github.com/paritytech/wasmi/issues/701).

_phantom: PhantomData<T>

The type parameter is used in the default implementation.

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Config> Debug for InstructionWeights<T>

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Config> Decode for InstructionWeights<T>where PhantomData<T>: Default,

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 InstructionWeights<T>

fn default() -> Self

We price both i64.const and drop as instr_i64const / 2. The reason for that is that we cannot benchmark either of them on its own.

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

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

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

fn size_hint(&self) -> usize

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

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

fn eq(&self, other: &InstructionWeights<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 InstructionWeights<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 InstructionWeights<T>where PhantomData<T>: TypeInfo + 'static, T: Config + 'static,

type Identity = InstructionWeights<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
