Struct Function

---

Structs ——-

struct Function has copy, drop, store

Fields

package_id: address

module_name: ascii::String

name: ascii::String

Struct MoveCall

Arguments are prefixed with:

• 0 for objects followed by exactly 32 bytes that contain the object id
• 1 for pure types followed by the bcs encoded form of the pure value
• 2 for the ApprovedMessage object, followed by nothing (to be passed into the target function)
• 3 for the payload of the contract call (to be passed into the intermediate function)
• 4 for an argument returned from a previous move call, followed by a u8 specified which call to get the return of (0 for the first transaction AFTER the one that gets ApprovedMessage out), and then another u8 specifying which argument to input. Following are some example arguments:

  0x06: &mut Clock = 0x0006,
  0x810a8b960cf54ceb7ce5b796d25fc2207017785bbc952562d1e4d10f2a4b8836: &mut Singleton = 0x00810a8b960cf54ceb7ce5b796d25fc2207017785bbc952562d1e4d10f2a4b8836,
  30: u64 = 0x011e00000000000000,
  "Name": ascii::String = 0x01044e616d65,
  approved_call: ApprovedMessage = 0x02,
  payload: vector<u8> = 0x03
  previous_return: Return (returned as the second argument of the first call) = 0x40001,
