solidity return array of struct
To return an array of structs in Solidity, you can define a struct and then create an array of that struct type. Here's an example:
pragma solidity ^0.8.0;
contract MyContract {
struct MyStruct {
uint256 id;
string name;
}
MyStruct[] public myArray;
function addStruct(uint256 _id, string memory _name) public {
MyStruct memory newStruct = MyStruct(_id, _name);
myArray.push(newStruct);
}
function getStruct(uint256 index) public view returns (MyStruct memory) {
require(index < myArray.length, "Index out of range");
return myArray[index];
}
}
In this example, we define a struct called MyStruct
with two fields: id
of type uint256
and name
of type string
. We then create an array of MyStruct
called myArray
. The addStruct
function allows you to add a new struct to the array, and the getStruct
function allows you to retrieve a struct from the array by its index.
Please note that this is just a basic example, and you can customize the struct and array to fit your specific needs.
