I need to create an array of structs for a struct that looks like this:

struct myStruct {
   address _address;
   uint _num;

And I need to create the array from function args.

I'm doing this by using 2 params (address[] & uint[]) that represent the 2 struct members, and for looping through them to create the array of structs. Is there a simpler way? Potentially using

  ['address', 'uint'],
  [<address>, <number>]

you don't have to encode it.

you can build the input like this:

   let  myStruct = {
    _address: accounts[2].address,
    _num: web3.utils.toWei("1")

Then just call your function with the struct as the input

  • It will actually be an array of structs that will be saved to storage. Is there a way, other than for looping, to save a struct[] memory arg to struct[] storage?

    haven't done that personally, so wouldn't know, but I doubt it. I've had troubles even doing arrays in a struct
