Struct noble_contracts::InstructionWeights [−][src]
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 execptions:
- If there is a i64 and a i32 variant of an instruction we use the weight of the former for both.
- 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
- 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
- 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.
