}

Describes the weight for all categories of supported wasm instructions.

There there is one field for each wasm instruction that describes the weight to execute one instruction of that name. There are a few exceptions:

1. If there is a i64 and a i32 variant of an instruction we use the weight of the former for both.
2. The following instructions are free of charge because they merely structure the wasm module and cannot be spammed without making the module invalid (and rejected): End, Unreachable, Return, Else
3. The following instructions cannot be benchmarked because they are removed by any real world execution engine as a preprocessing step and therefore don’t yield a meaningful benchmark result. However, in contrast to the instructions mentioned in 2. they can be spammed. We price them with the same weight as the “default” instruction (i64.const): Block, Loop, Nop
4. We price both i64.const and drop as InstructionWeights.i64const / 2. The reason for that is that we cannot benchmark either of them on its own but we need their individual values to derive (by subtraction) the weight of all other instructions that use them as supporting instructions. Supporting means mainly pushing arguments and dropping return values in order to maintain a valid module.

Fields

version: u32

Version of the instruction weights.

Note

Should be incremented whenever any instruction weight is changed. The reason is that changes to instruction weights require a re-instrumentation in order to apply the changes to an already deployed code. The re-instrumentation is triggered by comparing the version of the current schedule with the version the code was instrumented with. Changes usually happen when pallet_gear is re-benchmarked.

Changes to other parts of the schedule should not increment the version in order to avoid unnecessary re-instrumentations.

_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

Returns the “default value” for a type.

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 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, )
