Class CostModel

The execution of plutus scripts consumes resources. To make sure that these scripts don't run indefinitely or consume excessive resources (which would be harmful to the network), Cardano introduces the concept of "cost models".

Cost models are in place to provide predictable pricing for script execution.

It's a way to gauge how much resource (in terms of computational steps or memory) a script would use.

set

set(operation: number, cost: number): void
Sets the cost for the given operation.
Parameters
- operation: number
  
  The operation to get the cost for.
- cost: number
  
  The cost of the operation.
Returns void
