Documentation
data CostingFun model Source #
A type of costing functions parametric over a model type. In practice the we have one model type `ModelNArguments` for every N, where N is the arity of the builtin whose costs we want to model. Each model type has a number of constructors defining different "shapes" of N-parameter functions which calculate a cost given the sizes of the builtin's arguments.

Instances
class UnimplementedCostingFun a where Source #
In the initial stages of implementing a new builtin it is necessary to
provide a temporary costing function which is used until the builtin has been
properly costed: `see CostModelGeneration.md`. Each `ModelNArguments` type
defines an instance of this class where unimplementedCostingFun is a
constant costing function which returns a very high cost for all inputs.
This prevents new functions from being used in situations where costs are
important until a sensible costing function has been implemented.

class Eq a ⇒ Hashable a Source #
The class of types that can be converted to a hash value.
Minimal implementation: hashWithSalt.
Hashable is intended exclusively for use in in-memory data structures.
.
Hashable does not have a fixed standard.
This allows it to improve over time.
.
Because it does not have a fixed standard, different computers or computers on different versions of the code will observe different hash values.
As such, Hashable is not recommended for use other than in-memory datastructures.
Specifically, Hashable is not intended for network use or in applications which persist hashed values.
For stable hashing use named hashes: sha256, crc32, xxhash etc.
If you are looking for Hashable instance in time package,
