execute(list, struct | map) :: boolean | {:error, Predicator.InstructionError.t | Predicator.ValueError.t}
execute/2 takes an instruction set and context struct
Example instructions sets:
iex> execute([[“lit”, true]]) true
iex> Predicator.Evaluator.execute([[“load”, “age”], [“lit”, 18], [“compare”, “GT”]], %{age: 19}) true
iex> Predicator.Evaluator.execute([[“load”, “name”], [“lit”, “jrichocean”], [“compare”, “EQ”]], %{age: 19}) {:error, %Predicator.ValueError{error: “Non valid load value to evaluate”, instruction_pointer: 0, instructions: [[“load”, “name”], [“lit”, “jrichocean”], [“compare”, “EQ”]], stack: []}}
